Connecting Mutiple Tables with One Form

[airforce]

Now this is a little bit different:

Before: I wanted to call only one form (frmCommon) using by menu "Menu1" i.e. "mnuCSB_Click", "mnuCRB_Click()"

Now: The form (frmCommon) which appears after clicking mnuCSB_click. From this particular form, I want to call only one "Report.dsc". This form have only one command button with the name "cmdReport". How can I use only 1 command button "cmdReport" to show data from different tables.
