setDeaults for several radio button groups..

Hi! I have problems with setting the default vaule for radiobuttons.. I have a set of 30 rows with radiobuttons.. each group is named type_0, type_1.. If I just have one set of group there is no problem setting the detault value for the radio buttons.. But as soon as there are several they are all set to the last value I feed in to my defaultValues array.. $defaultValues = array(); for($i=0; $i<$playlist_maxItems; $i++) { if($i == 0) { $defaultValues["type_$i"] = "Live Session"; } else { $defaultValues["type_$i"] = "None"; } if(($i + 1)== $playlist_maxItems) $defaultValues["type_$i"] = "Selected Remix"; } $form->setDefaults($defaultValues) I print out the array and get Array ( [type_0] => Live Session [type_1] => None [type_2] => None [type_3] => None [type_4] => None [type_5] => None [type_6] =>... But why is type_0 not set "to Live Session" in the form? It is set to "Selected Remix". Please let me know if there is any solution to this as I spent several days on trying to solve this. PS. The setDeault stuff works for all textfields I have in the same form. Thanks in advance!
