Bugs in my script

Okay, THIS one I can’t figure out…
its reallly hard to explain,. because I don’t know the problem.

See, I have these 8 buttons which move a white bar…
It works, but after pressing a different white button, it starts moving much less…
you really need to see it.

Note that the xml won’t work because the link is to a file on my computer.

Thanks for the help (if you actually will this time:upset: )
