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.
