How do I separate multiple items in a single line text held in a collection?

I have a single line textbox that has location codes separated by ;

My form uses a list lookup that connects to this single line text field to hold all location codes selected.

I placed it in the a collection using a regular expression by using the split method and placing in the collection.

When I use the for each to log history, it only does it once and shows all the location codes instead of on a separate line.

Am I separating this right? How do I call on the collection to grab these individually?

Example in collection - "12;11;14;2011"
