Please Help... :(

Trouble with a script…

I got this script from flashstar.de, it’s a german website, but I am alright since i can understand a little german, but i need to disable all movement attempts on the Y axis, but I am a newbie, so i don’t know how…

(EDIT: Also, how would i go about linking all of the spawned menu buttons to an external text file? I know the original way of doint it, through an embedded button, but i dont know how through a moving one that is spawned like this…)

Quick German Lesson for those who will need it:
zentrum - Center
farb - Color
Skala - Scale
wert - Worth
tiefe - deep
gesamt - entirely
faktor - factor
