SShefer,
Was your question about defining the criteria or having a dropdown list of values to select as criteria?
ToeShot's guidance will define the criteria for the query.
If you want a dropdown on your switchboard so you don't have to type, add a combo box with the wizard.
In answer to the questions the wizard asks:
1.) You want the combo box to look up the values in a table or query.
Next >
2.) Select the View Queries radio button and select your query.
Next >
3.) Select the field you want displayed.
Next >
4.) Adjust the width of the column. Next >
5.) You want to "Remember the value for later use.'
Next >
6.) Type in the label caption.
Finish >
In the Properties pane, Data tab, look at the Combo Box's Row Source. EG:
Code:
SELECT DISTINCTROW[qryCustomerAddress].[PostalCode] FROM [qryCustomerAddress]
To eliminate the repeated values in the list, change the word DISTINCTROW to DISTINCT.
Then, do what ToeShot said.
