Display "other" value from Checkbox set

In FileMaker 14, I have a checkbox set that allows the user to enter other values aside from the assigned value list.

I'm trying to figure out how I could display the "other" text that is entered by the user, without also displaying other selected items, since those are visible in the checkbox set.

Can I somehow filter each value list item out and only display what is left in a text field?

Thanks for any suggestions.
