charging while dodging crashes the game?

I'm trying to make it so the user can't dodge while charging their energy. And they can't because if they try it crashes. If I press E to dodge, and press F to charge energy before the dodge script ends, is where the problem occurs. If someone could help me make it where you can't dodge while charging I would appreciate it.

uis.InputBegan:connect(function(input)--Charge
    if input.KeyCode == Enum.KeyCode.F then
        charging = true
        while charging == true do
        if dodging == false then
        game.Players.LocalPlayer.Character.Humanoid.Mana.Value = game.Players.LocalPlayer.Character.Humanoid.Mana.Value  + 1 
        wait() 
        if charging == false then return end
        if game.Players.LocalPlayer.Character.Humanoid.Mana.Value > 100 then game.Players.LocalPlayer.Character.Humanoid.Mana.Value = 100
end
end
end 
end
end)

uis.InputEnded:connect(function(input)--Stop charging
        if input.KeyCode == Enum.KeyCode.F then
        charging = false
    end
end)

dodging = false
uis.InputBegan:connect(function(input)--Dodge
    if input.KeyCode == Enum.KeyCode.E then
      if dodging == false then
          gg = Instance.new("BodyForce")
          gg.Parent = Player.Character.Torso
          gg.Force = Player.Character.Torso.CFrame.lookVector*-20000
          Player.Character.Humanoid.Jump = true 
          dodging = true
          wait(0.1)
          gg:Destroy()
          wait (1)
          dodging = false
        end 
    end
end)
