Ammo going in the negatives?

So i'm making a gun and it's going good but i have a problem where if all of the ammo is a certain number then it's possible for it to go to the negatives. I've tried using math.floor but that didn't really work for me. I also tried checking the number with an if statement but it's really confusing and i don't really know how to fix it! Any help at all would be nice

Here is the part of the script that reloads which is where it needs fixing.

	uis.InputBegan:Connect(function(input)
		if script.Parent.Parent.Parent == char then
			if input.KeyCode == Enum.KeyCode.R then
				if script.Parent.Parent.Ammo.Value ~= script.Parent.Parent.MaxAmmo.Value and script.Parent.Parent.AllAmmo.Value > 0 then
					if reloaddebounce == false then
						reloaddebounce = true
						script.Parent.Parent.Sounds.Reload:Play()
						reload:Play()
						wait(3)
						script.Parent.Parent.Ammo.Value = script.Parent.Parent.MaxAmmo.Value
						script.Parent.Parent.AllAmmo.Value = script.Parent.Parent.AllAmmo.Value - script.Parent.Parent.AmmoLost.Value
						script.Parent.Parent.AmmoLost.Value = 0
						reloaddebounce = false
					end
				end
			end
		end
	end)

You need to add this: script.Parent.Parent.AllAmmo.Value == 0 to script.

--Fixed Code:
uis.InputBegan:Connect(function(input)
    if script.Parent.Parent.Parent == char then
        if input.KeyCode == Enum.KeyCode.R then
            if script.Parent.Parent.Ammo.Value ~= script.Parent.Parent.MaxAmmo.Value and script.Parent.Parent.AllAmmo.Value > 0 or script.Parent.Parent.AllAmmo.Value == 0 then --Here
                if reloaddebounce == false then
                    reloaddebounce = true
                    script.Parent.Parent.Sounds.Reload:Play()
                    reload:Play()
                    wait(3)
                    script.Parent.Parent.Ammo.Value = script.Parent.Parent.MaxAmmo.Value
                    script.Parent.Parent.AllAmmo.Value = script.Parent.Parent.AllAmmo.Value - script.Parent.Parent.AmmoLost.Value
                    script.Parent.Parent.AmmoLost.Value = 0
                    reloaddebounce = false
                end
            end
        end
    end
end)

If still doesn't works, Post a comment.
