Having trouble writing an addon

[WhiteWolf87]

I am trying to set it up so that the addon checks to see if this character has installed this addon before. If the character did not install the addon then it brings up an installation frame. I know I'm probably missing something super easy, but I would appreciate the help... I've tried ready through World of Warcraft Programming, have spent 3 days reading forums and working on this... figured it was time to ask for help lol. I thought I would try looking at other addons to see how they did and used some of their code, but it isn't working right.

Note: Reworking the code, will get back to you.
