So me and my friend have been trying to make a Working PC on a in game monitor (surfacegui) its been working so far except for this one script.
If anyone can help thats ok. Can't post the entire script on here for some reason. Here it is anyways.

It seems like you are doing something wrong here as is but, regardless, this wouldn't work. Use Vector3. You can learn anything and everything you need to know about it here. It might seem complicated on first glance but trust me, it's not.
