Control linked to subform is readonly

[degras]

I have a form with a subform displaying data from a related table. Unfortunately there is not room across for all the fields on the related table. So I put an extra control on the form with the Control Source set to [TasksSubform].[Form]![Priority]. OK, so when browsing the data on the subform the data in the extra control changes accordingly, great. The problem is that the extra control is readonly, when I try to edit its value it say "control cannot be edited it's bound to the expression." How can I allow the extra control to be editable? Or is there another way to do this?



Thanks.

I would display the "important" fields in the SubForm with the SubForm in Continuous Form mode and add a CommandButton to the SubForm that pops open another Form in Single Form mode to edit all of the fields in the RecordSource of the SubForm. But that's just me.
