Combo Box-can't select item from list

[Rick]

I have two combo boxes on a form, one is populated by a
value list, the other by a query. Both populate fine and
all items show in drop down. The problem is the combo
box populated by the query will not let me select an item
for the list. The other works fine.

Is that combo box bound to a field in the form's record source? And is the
form's RecordSource a query? And is that query not updatable?
