Fill a prompt from listbox

Hi all

I'm using D.S 1.3 over UNX

I have a list box with years and I have a data source with a prompt over years with select "in list" (multiselect)

I want to fill the prompt with selected items from the list box

When I do it with single selection it works fine, for some reason when I try to fill the prompt with several items using for each loop,

it does nothing

Any ideas?
