Keep pupping up "Enter Parameter Value"

[SF]

Hi,

I have this main form and a subform. When entering a value in the main form,
the subform is supposed to display the related record.

Now I have this problem: When pressing Enter after I have entered a value in
the main form, the subform displays the correct record, but it also pups up
a message - "Enter Parameter Value".

Where shall I look to get rid off this pup-up?

The query on which the subform is based must have a parameter in it. If it's
referring to a control on an opened form, make sure you don't have a typo in
it.
