I've got an application that was working fine until a couple of weeks ago, but is now not working I'm afraid.  

I have a form called "Games".  The only field in this form is "GameDate".  This is a date field.

I have another form called "Results".  This has a lookup field called "Game", which references the "GameDate" field of the "Games" form.

When I look at the view for the "Results" form, I can see that the reference to "GameDate" is working fine.  When I *View* one of the records, the "GameDate" field is populated correctly.  But when I *Edit* the record, the "GameDate" field is not populated at all (drop-down box just shows "- Select -").

I've shared the application with support.  The URL is "https://creator.zoho.com/katieboyle598/golf-test"

Any help much appreciated!

Cheers, Katie
