Solved Can't exit subform

[Kayleigh]

I have a weird problem. I have onChange event of one field which triggers a pop-out input form. When the input is saved, it should update the original form.
My issue is that when I return to the original form (which is a subform), I can't click out of the subform to save the changes. I tried so many options but currently the only way to is to force the form to close and I get an error message.
Is there any way to resolve this? (See DB enclosed)

How does one recreate the issue? There is no change event in VBA, so perhaps it's a macro?

when I first clicked on the combo box dropdown in the subform i got this error. not sure if that can help or not. but it looks like one too many deletions have occurred:

your control rowsource is qrylkpStaffAdmin - however your db does not include any queries

Sorted. It was an after update event which wasn't completed.
