Problem with some maths and positioning

[Dzsozi (h03)]

Hello community! I've got a script from my friend, and I edited it as GTA V's notifications:

My only problem is that I got some problem with the maths, that I can't find, and I don't know how to fix the problem. I've tried several things, but none of them worked. It always had a little bug. The current version looks like this:

I would be very thankful if someone could fix this for me!
