I have a table of (Reagents), that has a check box In Use. How do I create a field on a form that only allows a user to select the "In Use"? Thank you.
Use the query wizard: you will need to use fields Reagent (name/id) and the yes/no. On this second column on the criteria you will define the criteria you want. Then, on the combobox wizard, use the query as source.
