from your image, can't see that frm_pat is open. What you appear to have is effectively a subform on frmStud which might be your frm_pat. However no idea how you might reference it since it is not a true subform. If it was the reference would be something like
forms!frm_stud.form.nameofsubformcontrol.form.studyid_pk
or
parent.nameofsubformcontrol.form.studyid_pk
forms!frm_stud.form.nameofsubformcontrol.form.studyid_pk
or
parent.nameofsubformcontrol.form.studyid_pk
