put some print statements, it could be that it just can’t find the animation ID or you set the animation ID to the wrong thing.

hey skelly,
thanks for your help mate.

i chucked in some print statements here and this is what i’m getting from the output. it appears to be spamming the play function on my animations. multiple times.

my print statements:

			if Close == false then
				animationID = "http://www.roblox.com/asset/?id="..animationIDTable["LowerHurleyAnim"]
				animation.AnimationId = animationID
				animTrack = somedudethatfollowsuHumanoid.Animator:LoadAnimation(animFolder.animation)
				animTrack:Play()
				print(animation.AnimationId)
				animTrack.Ended:Wait()
				animationID = "http://www.roblox.com/asset/?id="..animationIDTable["FriendlyRunAnim"]
				animTrack:Play()
				print(animation.AnimationId)
				
			elseif Close == true then
				animationID = "http://www.roblox.com/asset/?id="..animationIDTable["RaiseHurleyAnim"]
				animation.AnimationId = animationID
				animTrack = somedudethatfollowsuHumanoid.Animator:LoadAnimation(animFolder.animation)
				animTrack:Play()
				print(animation.AnimationId)
				animTrack.Ended:Wait()
				animationID = "http://www.roblox.com/asset/?id="..animationIDTable["AggressiveRunAnim"]
				animTrack:Play()
				print(animation.AnimationId)
			end

			if randomNumber == 1 then
				if not canJumpDB then
					canJumpDB = true
					somedudethatfollowsuHumanoid.Jump = true
					canJumpDB = false
				end
			end
			
		else
			print("test")
		end
	end)

try to change line 110 to this

if animTrack and animTrack.IsPlaying then

else statement

else
	if animTrack and animTrack.IsPlaying then
		animTrack.Stop()
		animationID = nil
		animation.AnimationId = nil
	end
end
