Backpack accessory clone falls down, when parented to character?

Hello guys, my problem is that I created a backpack, and a gui shop for an upcoming game. The problem is, that the localscript in the gui clones the backpack accessory, but it falls down. I tried a normal script from workspace, it works, i click the part, and the backpack is on my back. I don't know what to do, what do you think, what is the problem?

The script is not disabled, I tried it with a normal script, it wont work either.

You have to rename the object in tool to "Handle" which you want to hold. It must have Capital letter H and exactly as I have shown.
