DataGrid error

[andrew at midwestcoastmedia.com]

A published mobile app built using LC8.1.8 that suddenly stopped  
working. It retrieves info from a database and populates a few  
datagrids. I was able to use the Remote Debugger to pinpoint where the  
error is occurring (worth every penny of the upgraded license) and  
found this:

I tried to insert some breakpoints (virtual and hard coded) before the  
script that set the dgText so I could figure out what the bad data was  
but they weren't getting triggered. Can anyone shed some light onto  
this error while I backtrack the changes made recently since this  
worked (yesterday).
