I have a query which pulls its parameters from a Form [Main] to preform a search. One of the fields the query searches by is a Combo Box/Dropdown list [Combo94]. All Records have five possible results for this field (call them "A"-"E" to make it easy).
I want to make it so that when performing the search the user can either, select one of the five options (A-E), or they can select a sixth option "All", which will select all records (effectivly ignore this criteria). Currently I have the criteria set to [Forms]![Main]![Combo94] which obviously works when options A-E are used.
If it makes a difference, this query runs a search on five other fields at the same time.
Thanks,
Alex
