Awards / Achievements problems

I have an awards system I'm working on using information that I found on here, by creating a section that shows up on the profiles and side bars of members, and I can add in a medal for everything that they achieve.

However, when I add images to the image list for the awards, the result is that I can only choose one award per person, and not select multiple awards (which is what I want to do).


Please advise!

It seems like other people have got this same method, and it works with multiple achievements, though.
