Are you sure you have the master-child fields set for the subform? Is the
combo one of the fields in the subform?

I have made one of my fields in a subform a combo box. When I open the form
in form view, everything looks ok, but when I open the drop-down arrow and
make a selection, an error window immediately opens. This is the message:

You can't assign a value to this object.
*The object may be a control on a read-only form.
*The object may be on a form that is open in Design view.
*The value may be too large for this field.

I can hit the Return key and move on to the next field and the selected data
stays in the field. Can anyone help in resolving this error?

Thanks in advance!
