Can anyone help troubleshoot this tool? -Unsolved-

So i have a tool, and if you click, it swings and does damage, but if you press F, it only work in studio test mode. Could anyone help?

script.Parent.Equipped:connect(function(mouse)
	print("Equipped")
	mouse.KeyDown:connect(function(key)
		
		if key=="f" then
			
				print("Keydowned")
				local char=script.Parent.Parent
				local plr=game.Players:GetPlayerFromCharacter(char)
				script.Parent.GripUp=Vector3.new(-1, 5, -0)
			a=Instance.new("Part")
			a.Parent=game.Workspace
			b=Instance.new("PointLight")
			b.Parent=a
			b.Range=20
			if plr.TeamColor==BrickColor.new("Bright yellow") then
			b.Color=Color3.new(255/255, 239/255, 5/255)
			elseif plr.TeamColor==BrickColor.new("Dark green") then
				b.Color=Color3.new(25/255, 144/255, 17/255)
			end
			a.CanCollide=false
			a.Transparency=.4
			a.BrickColor=BrickColor.new("Bright yellow")
			a.Shape="Ball"
			a.Size=Vector3.new(.5,.5,.5)
			a.Position=script.Parent.Gun.Position
			a.Velocity=script.Parent.Parent.Head.CFrame.lookVector*math.random(300,500)
			script.Parent.GripUp=Vector3.new(-1, 0.01, -0)

			debounce2=false
			a.Touched:connect(function(hit)
				if hit.Name==script.Parent.Parent.Parent.Name then
				if debounce2==false then
					debounce2=true
				if hit.ClassName=="Hat" then
				debounce=false
				elseif hit.Parent:FindFirstChild("Humanoid") then
					hit.Parent.Humanoid:TakeDamage(100)
					wait(2)
					debounce=false
				else
					wait(2)
			debounce=false
					end
				end
				end
			
			end)
			
			
		end
	end)
	
end)

LocalScripts run their methods at different times than normal Scripts, which can mess things up. It works in Test Mode because all scripts run locally on Test Mode. All you have to do is add a short wait at the beginning of your script and it should fix. Ex:

wait(1)
-- Script here.
