Valid if dropdown not working

[skedaddlephil]

Hello,

I'm an appsheet newbie.  I've spent two days trying to get a Valid_If dropdown to appear, but my view is just blank.

I have a table Role.  It has a list of (business) roles in a column titled Role.  The type is Text.

I have a filter table Filter.  It has a column Role.  The type is EnumList with a base type of Text.  Allow other values is checked.  

I created a view based on Filter with the column Role set for quick edit and in the column order section.

I then add that view to my dashboard.  However, when I save and reload the app, the page says "No Items".  Doesn't show the selection box at all.

Hopefully this is enough info to explain my problem.

Thanks,

Phil
