fighting with Infomaker V12.1

I just installed Infomaker V12.1 and am working in our Test database in V11 on a custom tab.

My problem is with check boxes.  They seem to be requiring a value.

In my original file I specified the following values and somehow it worked:

EDIT - DATA VALUE FOR ON = 1

EDIT - DATA VALUE FOR OFF = 0

GENERAL - TAG = 'N'

This no longer works for Tessitura V11/Infomaker V12.  I have tried just about everything but can seem to get it to insert a default value of 0 for these check boxes and it won't let me save in the application until I specify a value.  I searched the Infomaker documentation but found nothing.

Would love to hear if anyone else had this issue.

As a last resort I'm thinking of adding a trigger to my custom table to insert the default value of 0 for these check box fields but there must be another way.

Thanks!
