How to I keep it from Reloading?

function Reload()
	if Cooldown==true then return end
	if (GoalPercent~=0) and (TargetCFrame~=GunHolds["Camera_Zoom"][2]) then return end
	Cooldown=true	
	TargetCFrame=GunHolds["Camera_Reload"][2]
	GoalPercent=1
	ggoaly=math.rad(-15)
	wait(0.25)
	for i = 0,0.9,0.09 do
		TransitionWeld(LArmCFs["L_Arm"][2],LArmCFs["L_RP_Trans"][2],armW,i)
		TransitionWeld(GArmCFs["L_Arm"][2],GArmCFs["L_RP_Trans"][2],garmW,i)
		wait()
	end
	ggun.c1.Transparency=1
	gun.c1.Transparency=1
	Sounds["Reload"]:play()
	for i = 0,0.9,0.09 do
		TransitionWeld(GArmCFs["L_RP_Trans"][2],GArmCFs["L_RP_1"][2],garmW,i)
		TransitionWeld(LArmCFs["L_RP_Trans"][2],LArmCFs["L_RP_1"][2],armW,i)
		wait()
	end
	wait(0.25)
	for i = 0,0.9,0.1 do
		TransitionWeld(GArmCFs["L_RP_1"][2],GArmCFs["L_RP_2"][2],garmW,i)
		TransitionWeld(LArmCFs["L_RP_1"][2],LArmCFs["L_RP_2"][2],armW,i)
		wait()
	end
	gun.c1.Transparency=0
	ggun.c1.Transparency=0
	needs=(script.PerClip.Value-script.InClip.Value)
	script.TotalAmmo.Value=script.TotalAmmo.Value-needs
	script.InClip.Value=script.InClip.Value+needs
	wait(0.05)
	for i = 0,1,0.15 do
		TransitionWeld(GArmCFs["L_RP_2"][2],GArmCFs["L_RP_3"][2],garmW,i)
		TransitionWeld(LArmCFs["L_RP_2"][2],LArmCFs["L_RP_3"][2],armW,i)
		wait()
	end
	wait(0.25)
	for i = 0,1,0.25 do
		TransitionWeld(OtherParts["Reload1"][2],OtherParts["Reload2"][2],OtherParts["Reloader"][3],i)
		TransitionWeld(GArmCFs["L_RP_3"][2],GArmCFs["L_RP_4"][2],garmW,i)
		TransitionWeld(LArmCFs["L_RP_3"][2],LArmCFs["L_RP_4"][2],armW,i)
		wait()
	end
	for i = 0,1,0.25 do
		TransitionWeld(OtherParts["Reload2"][2],OtherParts["Reload1"][2],OtherParts["Reloader"][3],i)
		TransitionWeld(GArmCFs["L_RP_4"][2],GArmCFs["L_RP_3"][2],garmW,i)
		TransitionWeld(LArmCFs["L_RP_4"][2],LArmCFs["L_RP_3"][2],armW,i)
		wait()
	end
	wait(0.25)
	for i = 0,1,0.05 do
		TransitionWeld(GArmCFs["L_RP_3"][2],GArmCFs["L_Arm"][2],garmW,i)
		TransitionWeld(LArmCFs["L_RP_3"][2],LArmCFs["L_Arm"][2],armW,i)
		wait()
	end
	wait(0.1)
	ggoaly=0
	GoalPercent=0
	Cooldown=false
end

This reloads and makes the TotalAmmo in my guns go negative numbers instead of staying at 0 how do I fix that?
