You can use arithmetic, string, comparison operators and functions within the calculated [[Custom Field|custom field]].
* References to other fields are always enclosed in square brackets: '''[variable1]'''. For example: '''[Salary]'''.
* The calculations are performed when you click the '''Save''' button and save the page.
* 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.
===Arithmetic Operators===
All values are treated as strings. For arithmetic operations, PARSEINT and PARSEFLOAT function are used to convert the string value to a numeric value.  For example: * '''PARSEINT([Salary]) + PARSEINT([Bonus]) + PARSEINT([Car Allowance]) ''' - Add Salary to Bonus to Car Allowance and return an integer result. * '''PARSEFLOAT([Salary]) / 26 ''' – Divides the Salary by 26 to show a bi-weekly amount.Exercise – ==Adding a Calculated Field== 1. Add a [[Custom Field ]] Type named '''Total Compensation ''' to the '''Compensation ''' tab. 2. Set the '''Field Type ''' to '''Calculated Value'''. 3. Add the following formula:
4. Set the '''Number Format ''' to '''Currency'''. 5. Save the '''Field'''. 6. Add another field named '''Pay Per Period ''' as shown below. 7. Set the '''Number Format ''' to '''Currency'''. The '''Field ''' list will look as follows:
8. Edit an '''Employee ''' record. 9. Click the '''Compensation ''' tab.
The calculated fields are blank as the record has not been saved with these fields.
 10. Click the '''Save ''' button. 
The values are calculated and saved.
=Web Page View Field= The [[Custom Field Type (110): Display Only – Web Page View|Web Page View ]] field provides the ability to display a fully formatted document or web page. In constructing this type of field HTML is used in conjunction with the following variables. 
In this example you will create a simple letter of offer displaying the employee’s name and address plus details of their compensation.
 1. Edit the '''Letter of Offer Field ''' field – currently set to a '''Link Single File Field''' field. 2. Change the '''Field Type ''' to [[Custom Field Type (110): Display Only – Web Page View|Display Only – Web Page View]].
The HTML Template is used to store the body of the document and will be a mix of HTML code, static text and references to fields associated with the underlying [[Entity|entity ]] – in this case the [[User|user ]] [[Entity|entity ]] and the employee [[Role|role]]==Basic HTML Tags RequiredThe following basic HTML tags should be added to the Web page View.==

Document Options
 You control which options are available to the user of each Web Page View field. Each of the selected options will add a button to the top of the Web Page View field. The following example shows how the field will look with all options enabled:
• Show Menu – check box that defines if a menu should be shown in the document window.

The final custom field type will be the Multiple Files Field. This field stores multiple files into a single field and is used to store:
• Uploaded documents.
