Cash Rec Entry Error

Anyone have an idea of what this error means? It is popping up when I click Apply to apply cash to an invoice.

Do you have to check the box in the Selected column?

I had it checked and then I clicked Apply and I guess it unchecked itself. It seems to function the same way in the base form so I don’t think that is the issue. It is weird because I get the error but the cash applies correctly and allows me to post the group.

All I had to do was Reset the Layout to Base. The form had apparently been sorted at one time and it was messing up the selection.
