I have five core table say as tbl1,tbl2,tbl3,tbl4 and tbl5, they all are linked with one table say as tblMain. There are five forms as frm_tbl1,frm_tbl2,frm_tbl3,frm_tbl4 and frm_tbl5, in all of these there is a field Sou that need to get value from frm_tblMain. frm_tblMain open when the click event occour in Sou field which open this form, user select the Sou and that value have to pass to previous form. As there are five form is there a way to pass value from one main form to all of this depending upon which form is open. If frm_tble1 is open it should pass to that form ,if other is open to other so on.
