Animation Plays In Studio Fine But Not In Game?

I've been having this problem for quite a while. I'm relatively new to animating and scripting via animations, and I've encountered a very severe problem. The animation works just fine in Studio, but playing them in-game (which I am trying it on Voids Script Builder) doesn't animate my character. It only loops the current animation playing.

What I had tried is disabling the animate script in my character, which did not fix the problem.

local idle = Instance.new("Animation")
idle.AnimationId = "http://www.roblox.com/Asset?ID=1103257041"
local idletrack = human:LoadAnimation(idle)
idletrack:Play()

--Human is the humanoid

Also, no errors are produced. The animation plays as soon as the script is ran.

This is because Void Script Builder is sandboxed. What this means, is that they set certain things a script can do and not with setfenv(). This is like how you cannot kick players. For more info, go to here.

Hope this solves your problem!
