Help With FauxScrollFrame

[Wadsworth]

I'm trying to experiment with FauxScrollFrames but I cant get it working right. When it first loads the buttons have the "Test <RandomNumber>" text on them but it disappears every time I scroll.

I started out with code based on WoWWiki HOWTOMake a Scrollable List Using FauxScrollFrameTemplate and it worked at first. But I'm renaming everything so it makes sense more when I add everything else onto the frame. I've started over already and got the same result. I fairly certain I haven't left any of the old variables in there. When you 'scroll' all it does is reset the text on the 5 buttons right? so why would it work when it initially loads them but not after each scroll?

Anyway and help, tips, or pointers you can give would be greatly appreciated. Thanks in advance.
