Yeah, sorry I meant to update that - took a phone call between posting and realising my mistake!
I am getting another error when I run in the IDE -
AttributeError: 'Tabulator' object has no attribute '_columns'
at app/Tabulator/Tabulator/__init__.py, line 146 column 8
called from property.py, line 20 column 8
called from Form1, line 10
I’m looking into it but thought you should know.
