How do you get custom player animations?

I have this script, it works in studio, but not in the public game:

wait (0.5)
script.Parent.Animate.jump.JumpAnim.AnimationId = "rbxassetid://499413648"
script.Parent.Animate.walk.WalkAnim.AnimationId = "rbxassetid://500066544"
script.Parent.Animate.run.RunAnim.AnimationId = "rbxassetid://500066544"
script.Parent.Animate.fall.FallAnim.AnimationId = "rbxassetid://500074347"
script.Parent.Animate.idle.Animation1.AnimationId = "rbxassetid://500079699"
script.Parent.Animate.idle.Animation2.AnimationId = "rbxassetid://500082676"
script.Parent.Animate.toolnone.ToolNoneAnim.AnimationId = "rbxassetid://500092684"
script.Parent.Animate.climb.ClimbAnim.AnimationId = "rbxassetid://500108945"
script.Parent.Animate.sit.SitAnim.AnimationId = "rbxassetid://500116162"
script:remove()

It is located under the StarterCharacterScripts. I have tried the script as a Local Script and a Normal Script, but neither work. Any ideas?
