Hi. I hope its not too much to ask but I've been trying to create a crop harvestor skript. This is an item that when placed auto farms nearby crops and deposits the items in a chest. The code that I have created looks fine to me and when I run it it doesn't show any errors but for some reason it doesn't work. Here's the code:

every 10 seconds in "world":
   loop all blocks in {cropharvestor::*}:
      if block at location of loop-block-1 is a dropper named "&2&lCrop Harvestor":
#Wheat
         loop all blocks in radius 5 around the loop-block-1:
            loop-block-2 is fully grown wheat plant
            set loop-block-2 to wheat plant
            loop all blocks in radius 4 around the loop-block-1:
               loop-block-3 is a chest
               add 2 wheat to loop-block-3's inventory
               exit loop
#Carrots
         loop all blocks in radius 5 around the loop-block-1:
            loop-block-2 is fully grown carrot plant
            set loop-block-2 to carrot plant
            loop all blocks in radius 4 around the loop-block-1:
               loop-block-3 is a chest
               add 2 carrot to loop-block-3's inventory
               exit loop
#Potatoes
         loop all blocks in radius 5 around the loop-block-1:
            loop-block-2 is fully grown potato plant
            set loop-block-2 to potato plant
            loop all blocks in radius 4 around the loop-block-1:
               loop-block-3 is a chest
               add 2 potato  to loop-block-3's inventory
               exit loop
#Nether Wart
         loop all blocks in radius 5 around the loop-block-1:
            loop-block-2 is fully grown nether wart plant
            set loop-block-2 to nether wart plant
            loop all blocks in radius 4 around the loop-block-1:
               loop-block-3 is a chest
               add 2 nether wart to loop-block-3's inventory
               exit loop
 


command /cropharvestor:
   permission: op
   permission message: You are unable to perform this action
   trigger:
      give dropper named "&2&lCrop Harvestor" to player

on place of dropper:
   if player's tool is a dropper named "&2&lCrop Harvestor":
      set block to dropper named "&2&lCrop Harvestor"
      add location of block to {cropharvestor::*}

If someone could help me with this I'd be really grateful.
