Hi all,
It appears I'm having an issue trying to get values to populate in the custom columns where the table has subitems.

I've had my script work in a table without subitems where I set the custom column element = value, with no issues and it populated in the custom column so I'm wondering if the subitem row is what is causing issues.
My custom columns with values in the grid
but not appearing in the custom columns 
If anyone has any ideas or has experienced something similar, please let me know!
Thanks in advance
