Can someone help please!

[VandilFish]

The issue i'm having is sometimes when i lift the LeftMouseButton it continues to fire without pressing anything, it happen rarely but it happens. I do want it to auto fire and loop while holding down the leftMouseButton. Could anyone help me with this? Cheers!
Anyone that is able to help with this could you please explain what was wrong with it and maybe also fix it? Cheers!
