Click here to peruse our selection of custom fields.

General Description

Executes an expression to calculate a value and store the result.

Field Options

Option Description Format
Custom Field ID The unique ID number associated with the custom field. Not Applicable
Field Type The list of available Field Types. @fieldtype@
Field Name The name of the field, used internally to reference the user's input; @fieldname@
Caption  The leading question or prologue before the field. @caption@
Display Order  The order (relative to other fields) in which this field is displayed. @displayorder@
Description Definition and general description of the custom field. Will not be displayed. @description@
  • Label Display: Determines the location of the field caption. Options include: Left of Field, Above Field, No Caption, Hide Caption. Note: this option was previously called Label Display. (See examples here.)
  • Searchable: This field can be searched within the tracking application.
  • Track Changes: Keeps track of changes made to this field.
  • Hide Field: Field will be hidden.
  • On New Record: Controls how the field should be displayed until record has been saved once.
    • Always Display: Field will be exposed both before and after the record is saved.
    • Hide on New Record: Field will be hidden until record is saved.
    • Only Show on New Record: Field will be exposed until record is saved, and then it will be hidden. This option is useful for fields that provide instructions for filling out forms before saving.

Special Options for Field

Expression: Defines the expression to be executed

All values are treated as strings. For arithmetic operations, PARSEINT and PARSEFLOAT functions are used to convert the string value to a numeric value.

Example summing the values using five custom fields:

ParseFloat([Total Monthly Cost]) + ParseFloat([Total Cost Ex]) + ParseFloat([Hardware Rental]) + ParseFloat([Email]) + ParseFloat([Other])

If you are using this field in a "Dynamic Control Field" address the fields by their field ids with the following syntax:
  frm.cf_customfieldid.value 

Example: PARSEFLOAT(frm.cf_1254625.value)*0.44

Notes:

  • You can in general use either the name of the field within square brackets, or frm.cf_customfieldid.value to refer to the values for the calculations.
  • In both cases is that the field must be visible on the page (or a Hidden Value custom field that is on the page).
  • A Combo Box custom field can be used in mathematical as long as the stored value is numeric. The displayed value does not have to be numeric
  • Check Boxes cannot normally be used in Calculated Value fields. (They can be accommodated with sufficient knowledge of JavaScript)

Services

  • Enable Map Service: displays the map icon next to the field name that will launch the user’s selected map service and display a map of the content of the field
  • Enable People Search Service: displays the search Internet icon next to the field name that will launch a variety of search services and display the contact details from those services
  • Enable Organization Search Service: displays the search Internet icon next to the field name that will launch a variety of search services and display the organisations details from those services

Field Formatting Options

  • Number Format: Formats any numbers entered into this field
  • Style: Bold, Underline, Italic, Highlight
  • Tool Tip: Enter help text to be shown on mouse-over
  • Read Only: Checkbox
  • HTML Tag: Additional attributes to the field HTML tag
  • Visibility Condition: Conditions upon which the field is visible

Role - Field Permissions

These fields allow you to control by Role who is allowed to view and/or modify the field.

Status - Field Permissions

These fields allow you to control by the Status of the record whether or not the field can be viewed and/or modified.

Notes

You can use arithmetic, string, comparison operators and functions within the calculated custom field.

  • References to other fields are always enclosed in square brackets: [variable1]
  • The calculations are performed when you click the Save button and save the page.

Important Notes on Calculation Order

  • Calculated field formulas are executed in the same order that the calculated fields are displayed on the page.
  • You must not place fields that perform summary calculations based on other calculated fields ABOVE the subordinate calculations.
  • If the fields are ordered in this manner, saving the page will not update the summary calculation, as summary formula will be executed BEFORE the subordinate calculations are performed.

SmartSimple Calculated Field Operators

Arithmetic Operators

Rounding:

  • To round a calculation to 2 decimal places use the following syntax:
  • Math.round((expression)*100)/100
  • For no decimal places:
  • Math.round(expression)

where expression is the calculation to be rounded off, such as PARSEINT([variable 1])/PARSEINT([variable 2])

String Operators

Comparison Operators

Date Functions

calage([date of birth]) - Calculates the number of full years between the current date and the date included in the function.


Time Functions

To calculate the time difference for Standard Fields in hours and minutes use the following

Level 1:

  • timediff(frm.ostartdate.value,frm.oenddate.value,frm.ostarthour.value,frm.ostartminute.value,frm.oendhour.value,frm.oendminute.value)

Level 2:

  • timediff(frm.startdate.value,frm.enddate.value,frm.starthour.value,frm.startminute.value,frm.endhour.value,frm.endminute.value)

(note: the starttime and endtime Standard Fields are actually stored as part of the startdate and enddate fields, which is why they are used here)
