Why does "Jumped" always return false?

so im trying to make a spindash (ability from Sonic) script and i've run into a problem where if you hold shift in the air, the first half obviously doesnt execute, but if you then release shift after you landed the second half does execute, i tried to bandage this with a "Jumped" value that should be changed to true if the player holds shift while in the air. Yet it always returns false whenever i ask it to be printed

local UIS = game:GetService("UserInputService")
local Player =  game.Players.LocalPlayer.Character
local humanoid = Player.Humanoid 
local anim = Instance.new("Animation")
anim.AnimationId = "http://www.roblox.com/asset/?id=4491181250"
local counter = 157 --put the character's walkspeed here
local OrgWS = 157 --put the character's walkspeed here
local debounce = false
local playAnimA = humanoid:LoadAnimation(anim)
local Jumped = false 
UIS.InputBegan:Connect(function(inst)
  if not debounce then
   if humanoid:GetState() ~= Enum.HumanoidStateType.Freefall then
      if inst.KeyCode == Enum.KeyCode.LeftShift then
        debounce = true
        Player.HumanoidRootPart.Anchored = true
        playAnimA:Play()
        Player.TrailPart.Smoke.Enabled = true
        Player.TrailPart.Dirt.Enabled = true
         if inst.KeyCode == Enum.KeyCode.LeftShift then
            counter=counter-70
        end
        wait(0.5)
           if inst.KeyCode == Enum.KeyCode.LeftShift then
              counter=OrgWS+10
              wait(1)
                if inst.KeyCode == Enum.KeyCode.LeftShift then
                   counter=counter+35
                    wait(3)
                      if inst.KeyCode == Enum.KeyCode.LeftShift then
                      counter=counter+15
            else
                Jumped = true
end
        end
    end
end
end
end
end)

UIS.InputEnded:Connect(function(inst)
 if humanoid:GetState() ~= Enum.HumanoidStateType.Freefall then
   if Jumped == false then
    if inst.KeyCode == Enum.KeyCode.LeftShift then
       print("Jumped is" == Jumped)
          debounce = true
          Player.HumanoidRootPart.Anchored = false
          Player.TrailPart.Smoke.Enabled = false
          Player.TrailPart.Dirt.Enabled = false
          playAnimA:Play()
          humanoid.WalkSpeed = counter
          humanoid.JumpPower = humanoid.JumpPower +24
          Player.TrailPart.Trail.Enabled = true
          wait(1)
           if inst.KeyCode == Enum.KeyCode.Space then
            humanoid.WalkSpeed = humanoid.WalkSpeed -25
            humanoid.JumpPower = humanoid.JumpPower -24
            playAnimA:Stop()
           else
            humanoid.WalkSpeed = humanoid.WalkSpeed -10
            humanoid.JumpPower = humanoid.JumpPower -24
            wait(1)
            humanoid.WalkSpeed = humanoid.WalkSpeed -15
            wait(1)
            humanoid.WalkSpeed = OrgWS
            playAnimA:Stop() 
            Player.TrailPart.Trail.Enabled = false
            counter = 157
            OrgWS = 157  
            debounce = false      
        end
end
end
end
end)

here's is the localscript btw.
