Open multiple select_one fields based on select_multiple field answers.

I'm trying to open multiple select_one fields based on the answers from a select_multiple field. Works with one selection made, everything disappears when more than one selection is made. Is there a way to make this work?

Try using - selected(${parts},'1')
