QF: Dynamically generating radio groups?

Hi, How do I dynamically generate radio group names in my loop? I want my statement to look like this: $hhm_1_gndr[] = $HTML_QuickForm::createElement('radio', $i, null, 'Male', 'male'); and so on, through the end of my loop. I tried the variable variable code below but it didn't work. Maybe it's just a PHP syntax issue. ###### $gndr_grp_name = "hhm_".$i."_gndr[]"; $$gndr_grp_name = &HTML_QuickForm::createElement('radio', $i, null, 'Male', 'male'); $$gndr_grp_name = &HTML_QuickForm::createElement('radio', $i, null, 'Female', 'female'); $form->addGroup($$gndr_grp_name, 'hh_mem_gndr', 'Member’s Gender:'); ###### thanks in advance if you can help me.
