Can you tell me what's broken?

Ok, I kinda took a script and made huge changes to it, and they actually worked! But then I added the "Torso" Parts of the script and it broke it! Ok, look, this was in a LocalScript. AND IT WORKED Believe it or not. It worked, The original script you see was how it was originally made then i added the Legs in the script, and it worked. BUT when I added the Torso parts into the script it broke it. What exactly did I do wrong? At first it was Arm1 & Arm2 Only in there, then I added Leg1 & Leg2,saved it, tested, it worked. Tried to add a Torso clone and it broke it.Output said:

Is your script local? Local scripts can't use PlayerAdded. Also, If it's a regular script, regular scripts can't use LocalPlayer. That might be the error.
