So for the past few hours I have been Frankensteining a piece of skript code that is supposed to give the player 1 out of 4 possible blocks or items with different chances every 10 seconds. For some reason it doesn't work, If it's a simple fix that you know of, I'm sorry because I am not good at skript. If it's a hard fix, Im also sorry if this takes your time. If you can possibly find the problem with this plz tell me! Itemgiver.sk

I have been having problems trying to find out what the problem with this skript piece as when I reload it it says the 3rd line has an error with something. Is anything spelt wrong? Is there more code to add? Is there less code to have? I don't know. Heres the skript: on rightclick with coal: if name of tool of player is "&7specific name": execute console command "/give %player% gold_nugget {display:{Name:[{"text":"specific name 2"}]}}"
