I've read this entire thread and I'm still not quite sure I understand what the problem is.
My first guess, just from your original post is that you have Lvlpts set to zero, meaning clicking the link won't increase it. So it's doing exactly what you've told it to do. But if it's more complicated than that, than take a step back, and spell out exactly what it is that you're trying to do, and how you have it set up.
It's probably just something small you've overlooked. A variable increasing another variable is generally pretty simple. I know it must be, or I wouldn't be able to have gotten it working in my own game. :P
