Make this crawl animation have multiple parts?

I'm trying to make multiple parts to my crawl animation, these parts being:

• Begin Animation (Get onto the ground)

• Idle Animation

• Crawl Animation (Main animation)

• End Animation (Get up)

Issues:

• Whenever the key "C" is held down, the player is meant to play the Begin Animation the animation does not play, as the Idle Animation plays instead.

• The Idle Animation does play, but will not allow the Crawl Animation to play.

• The Crawl Animation does not play as stated above.

The *End Animation plays fine, but after it plays it goes straight to the Begin Animation starting it all over again.

Script:

Note: This script was taken originally as a free model but was edited to play multiple animations.

Player = game.Players.LocalPlayer
repeat
  wait()
until Player.Character
Mouser = Player:GetMouse()
name = Player.Name
char = game.Workspace[Player.Name]

AnimationIdle = script.AnimIdle
Animation = script.Anim
Begin = script.GetDown
End = script.GetUp

idletrack = char.Humanoid:LoadAnimation(AnimationIdle)
begintrack = char.Humanoid:LoadAnimation(Begin)
animtrack = char.Humanoid:LoadAnimation(Animation)
endtrack = char.Humanoid:LoadAnimation(End)

 
Mouser.KeyDown:connect(function(key)
  if key == "c" and char.Humanoid.Running == true then
      char.Humanoid.WalkSpeed = 0
      begintrack:Play()
      wait(1)
      animtrack:Play()
      char.Humanoid.WalkSpeed = 4
      char.Humanoid.JumpPower = 0
  else
      if key == "c" then
          idletrack:Play()
      end
          end
      end)
  
  Mouser.KeyUp:connect(function(key)	
   if key == "c"  then
      char.Humanoid.WalkSpeed = 0
      animtrack:Stop()
      endtrack:Play()
      char.Humanoid.WalkSpeed = 16
      char.Humanoid.JumpPower = 50
  end
end)

Script Hierarchy

Game > StarterGui > Crawl > AnimIdle, Anim, GetDown, GetUp

Thank you in advance if you can help!

I don't understand what are you want doing but try that

--< Services
local PlayerService = game:GetService('Players')
local UserInputService = game:GetService('UserInputService')

--< Variables
local Player = PlayerService.LocalPlayer
local name = Player.Name
repeat wait() until Player.Character
local char = Player.Character

local AnimationIdle = script.AnimIdle
local Animation = script.Anim
local Begin = script.GetDown
local End = script.GetUp

local idletrack = char.Humanoid:LoadAnimation(AnimationIdle)
local begintrack = char.Humanoid:LoadAnimation(Begin)
local animtrack = char.Humanoid:LoadAnimation(Animation)
local endtrack = char.Humanoid:LoadAnimation(End)

--< Events
UserInputService.InputBegan:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.Keyboard and input.KeyCode == Enum.KeyCode.C and char.Humanoid.Running == true then
		char.Humanoid.WalkSpeed = 0
		begintrack:Play()
		wait(1)
		animtrack:Play()
		char.Humanoid.WalkSpeed = 4
		char.Humanoid.JumpPower = 0
	elseif input.UserInputType == Enum.UserInputType.Keyboard and input.KeyCode == Enum.KeyCode.C then
		idletrack:Play()
	end
end)

UserInputService.InputEnded:Connect(function(input)  
	if input.UserInputType == Enum.UserInputType.Keyboard and input.KeyCode == Enum.KeyCode.C then
		char.Humanoid.WalkSpeed = 0
		animtrack:Stop()
		endtrack:Play()
		char.Humanoid.WalkSpeed = 16
		char.Humanoid.JumpPower = 50
	end
end)
