Issue with select multiple and jr:choice-name () in the repeat group

Hi, I have problem with jr:choice-name ().
My aim is to set a repeat count based on the count of items selected from a select_multiple field and then use the value from each selected item in the positions they are counted. All codes work well, but the value it shows only who choice name not label. So I converted select multiple using jr:choice-name (); now it only work if I select the first one of select multiple. if I select more than one - it show some thing like undefined. How should I solve this?
