From post 3: The only approach I can think of is a parameterized query where the combobox is referenced under each of the 14 fields, each on a separate Criteria row to invoke the OR operator (looks like stair steps).
LIKE operator is not useful without wildcard. Might as well just use = sign.
The criteria under each RawPartNumber field would be:
LIKE "*" & [Enter the part number you are looking for] & "*"
Or if you use a textbox or combobox for user to input the value:
LIKE "*" & Forms!formname!comboboxname & "*"
