If I have a text box named [States] on my [Workstation] form, and this text
box contains simple two-letter state codes with comma separators, for example
"AZ", "CO", "WA", etc, should I be able to reference this text box in the
criteria grid under a Project_State field with code along the lines of,
In(Forms![Workstation]![States])? I seem to be able to type only one state
reference into the text box with no surrounding quotes and receive a correct
return of data.

Thank you.
