Active Form as Query Criteria

Hi Everyone,

I have tried searching for the answer in this newsgroup, but I don't
think I have found an answer that works for me.

I have several forms that are populated by the same query however
criteria of the query which refers to a project id needs to be
dynamically populated with the active form name like so:

Criteria: Forms!ACTIVEFORMNAME!Project_Id

I have tried :

Criteria: Forms!Screen.Activeform!Project_Id

but that did not work.

Any help or guidance would be appreciated.
