To control how a barcode obtains data            

To define the properties of a barcode, you must first select the barcode. Set properties that control how the barcode obtains data in the Value tab of the Object palette.

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

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

•	To allow users to choose to enter data or not, select User Entered – Optional.

•	To prompt users to enter data and make the field recommended, select User Entered – Recommended and type a custom message in the Empty Message box.

•	To prompt users to enter data and make the field required, select User Entered – Required and type a custom message in the Empty Message box.

•	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 cannot 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 cannot edit the value.

2.	If the value is recommended or required, type a prompt in the Empty Message box.

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

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