Help with Vote Pads?

Here's the code:

V=0

game.Workspace.TextValue.Value = V
function Touched(Plr)
if game.Players[Plr.Parent.Name]~=nil then
V=V+1
game.Workspace.TextValue.Value = V
print(V)
end
end

function Ended(Plr)
if game.Players[Plr.Parent.Name]~=nil then
	
V=V-1
game.Workspace.TextValue.Value = V
print(V)
end
end
script.Parent.Touched:connect(Touched)
script.Parent.TouchEnded:connect(Ended)

It adds by one every time the player moves. Anyway I can make one player only add one vote rather than a vote every time the player moves around on the block or jumps. Thanks.
