I am having trouble with an order form, "TestOrderF", which has no subforms on it. Here is what is happening.  

When I open the order form from my customer form, the order is pulled up correctly, however I get a popup window asking for a "Parameter Value", which says:

"Forms!TestOrderF!CustomerID"

If I just click OK, I get an error message "Return without Gosub".

I looked to see if the field "CustomerID" on this form  is present, and sure enough it is.  I tried copying and pasting the "CustomerID" field on the form, and saving.  All of a sudden, everything works on the form.

Then, when I close, and reopen the database and go back to this form, I immediately run into this parameter issue when I scroll the form.  Again, copy and pasting "CustomerID" field fixes the issue.

It seems that as long as I don't close the database I am O.K.

Can anyone help with this problem. Thanks in advance.

The control on the form, what is its name?
Make sure it hasn't changed to textbox1 etc.
Try deleting it and adding it on from the add fields.
