Invalid argument #2 (Vector3 expected, got nil) on line 26, any help would be nice.

Your error is saying that the second argument is nil, meaning it isn’t defined. The error happens in the section CFrame.new(hitbox.Position, mousepos), where mousepos is the second argument. With the code provided we can’t see how you’re getting mousepos on the client, so I can’t help you much more than say to verify that you’re correctly passing your arguments because mousepos is clearly not defined.
