Looking for help with my first addon

[stypsy]

Hello,

I'm looking for help with completing my first addon. The part I'm having difficulty with is writing the code to display the information I requested. The following is the addon I'm creating and as you can see in the Update Functions section ... I'm at a loss. Below the lua lines I have posted the xml code that I'm hoping will display rank points.

The reason I'm writing this is because I prefer to see rank points earned / rank points required to next level. Both are available on the PvP window but it takes a few clicks to get too and you have to stare at a large window that blocks the action. This way, with the addon, I should have a small moveable window that displays rank points earned / rank points needed.

Any help would be greatly appreciated,

Sty
