I'm trying to make my mana intValue rise when I press g, it's not working?

I reread your code over and over and over again, and then I realized something, actually, a few errors... First of all(and the most important), you need to make the while true do part something like this: While charging == true and wait(.03) do

mana.Value = mana.Value + 1

end

And that's because the game has to keep looping through it seeing if it's true, if you just put "if charging == true then", it's only going to be looking at the origin value, not the new value! so here's what your code SHOULD look like: local RS = game:GetService("ReplicatedStorage") local RE = RS.ManaEvent local plr = game.Players.LocalPlayer local mana = plr:WaitForChild("Stats").Mana local charging = false

local function started(input,gameProcessed)
UIS.InputBegan:Connect(function(input, gameProcessedEvent)
    if input.KeyCode == Enum.KeyCode.G and charging == false then
    charging = true
end

end)

local function ended(input,gameProcessed)
UIS.InputEnded:Connect(function(input, gameProcessedEvent)
    if input.KeyCode == Enum.KeyCode.G and charging == true then
charging = false
    end
end)

UIS.InputBegan:Connect(started)
UIS.InputEnded:Connect(ended)


    while charging == true and wait(.03) do

    if mana.Value == 100 then
  mana.Value = mana.Value
  elseif mana.Value < 100 and charging == true then

mana.Value = mana.Value + 1

end

end

end

end

end
  end

end
