[ferro31]

Hey guys! I did a shop, and i can take out item from the shop and dont even taking away my points.
Heres the code: View attachment upload_2020-11-20_17-30-58.png
and if i try to click on it, i can just move around and get the block, place it down everything.
And i dont know whats the problem with the skript.
