To define the behavior of the check box

1.	In the Object palette, click the Value tab and select one of these options:

•	To allow users to choose whether to enter data, select User Entered – Optional.

•	To make the field read only and display a data value that is calculated and displayed through an attached script, select Calculated – Read Only. Users will not be able to edit the calculated value.

•

To make the field editable and display a data value that is calculated and displayed through an attached script, select Calculated – User Can Override. Users can edit the value if the calculation script has been written to accept the input. If a user does edit the calculated value, the custom message you specify in the Override Message box appears.

•	To make the field read only and display a data value that is merged or calculated and displayed at run time, select Read Only. Users will not be able to edit the value.

2.	If the value will be calculated, attach the calculation script to the object by using the Script Editor.

3.	(Optional) If a calculated value can be overridden, type a message in the Override Message box.

Tip:	You can dynamically populate a validation pattern or script message with a value from a data source. This allows you to ensure that users enter the correct value in the field.
