Data Validation for Combo Box Based on Query

[Ganymede]

I'm not sure if this is more of a form question than a query question.

I have a listbox on a form that allows the user to select one of several options from a query. But I want to make sure that the user only selects one of the options from the query results. I understand that the beforeupdate property can do this. But I'm not sure how to go about doing that.

From the sound of it, just make sure the multiselect property of the listbox is None.

I guess I could have tried that but I just made a "before update" if statement and that did the trick. Thanks though.

Less intuitive to me, but whatever works for you. As a user I might be annoyed if I was able to select more than one and then later got told I couldn't. That forces me to go back and unselect items to get back to one.

Where is the multiselect property? I've been looking all over for it

On the Other tab of the listbox properties.

Odd. It's not appearing in the 2013 version.

Oh. I know what I did. I called it a listbox instead of a combobox. Sorry. It's a combobox. Doh!

Thank you though.
