This feature uses JavaScript syntax

General Description

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

Field Options

• 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:

ssParseNum([Total Monthly Cost]) + ssParseNum([Total Cost Ex]) + ssParseNum([Hardware Rental]) + ssParseNum([Email]) + ssParseNum([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: ssParseNum(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)

• Visibility Condition: See the Visibility Condition Wiki page.
• Field Permission Matrix: See the Field Permission Matrix Wiki page.
• Services: When services are enabled, the caption of the field will acquire a dotted underline. The services can be accessed by hovering your mouse over the field caption.

• Enable Map Service: Enables the map icon that will launch the user’s selected map service (configured in Personal Settings) and display a map of the content of the field.
• Enable People Search Service: Enables the people search icon that will launch a variety of search services and display the contact details from those services.
• Enable Organization Search Service: Enables the organization search icon that will launch a variety of search services and display the organization's details from those services.

• Value Storage: Enables linking two different custom fields to the same user data. See Value Stores To page.
• Field Formatting Options: See the Field Formatting Options Wiki page.
• Role - Field Permissions: These settings allow you to control by Role who is allowed to view and/or modify the field.
• Status - Field Permissions: These settings allow you to control by the Status of the record whether or not the field can be viewed and/or modified. (Only present within the Universal Tracking Application)
• Type - Field Permissions: These settings allow you to control by the template of the record whether or not the field can be viewed and/or modified. (Only present within the Universal Tracking Application)

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

Note: To round to a different decimal place just change *100)/100 part as per requirement.

Example:To round to 3 decimal places, you would use Math.round((expression)*1000)/1000

• 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)
