The loop for the repeat selection on the index page seems about the same as the one on the fabrics page. When you try to edit it within the server behavior it gives you an error about the index?
You could add in some php code within the loop to have it print out the values as the display is being printed out to the page. Is it possible for you to post a copy of the db here so that we can test this out? If not I can open a ticket for you so we can exchange info in private.
