just replaced a window, now having an issue
 

I have a 2001 audi A4 quattro, had the window busted in and i just replaced it; however, when I do the one touch roll up it goes all the way up then rolls itself down about 4"... I tried resetting it (hold it down for a bit, then hold it up) but it continues to do the same thing. Can't seem to figure out what's going on.. Irritated please help.

Anybody?
I Would like to get this solved.. Sometime
