Check box properties in the Value tab

When you create a check box, the Value tab displays several options that you can apply to the object.

Type

Enables run-time calculations and prompts.

User Entered: Users may choose to enter data or not.
Calculated - Read Only: A data value will be calculated and displayed at run time through an attached script. Users will not be able to edit the calculated value.
Calculated - User Can Override: A data value will be calculated and displayed through an attached script. 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.
Read Only: A data value will be merged or calculated and displayed at run time. Users will not be able to edit the value.

Default

Sets the initial state of the check box.

On: The default state is On. The check box is selected initially.
Off: The default state is Off. The check box is deselected initially.
Neutral: The default state is Neutral. The box is filled with grey initially.
Note: The Default list is available only when the Type option is set to User Entered or Read Only. The Neutral option is available from the Default list only when the States area in the Field tab is set to On/Off/Neutral.

Validation Script Message and Error

Sets a custom message to display when an attached validation script detects an unacceptable value. By default, this situation causes a programming error to be generated at run time. To generate a warning instead, deselect the Error option. See To validate user input.

Note: This option is not available when the Type option is set to Protect, Calculated - Read Only, or Read Only. Validation Script Message is a dynamic property. Dynamic properties are identified by active labels that have a green underline that you can click to dynamically bind the property to a data source. To turn active labels on and off, use the Show Dynamic Properties command in the Object palette menu. See Dynamically populate a validation script message.

Form Level Validation Settings

Open the Forms Properties dialog box on the Form Validation tab. See Form Validation (Form Properties dialog box).

Override Message

Sets a custom message to inform users that they are changing the value of a calculated field. The message appears when a user changes the calculated value.

Note: This option is available only when the Type option is set to Calculated - User Can Override.
