This is the wrong section, move to the Configuration section.

 

[huntingzap]

Remove the -1 in the sell price section and leave it blank. That might fix it

 

[Asodey]

Remove the -1 in the sell price section and leave it blank. That might fix it

I will try this once I am on my pc, will update you![DOUBLEPOST=1571649353][/DOUBLEPOST]

Remove the -1 in the sell price section and leave it blank. That might fix it

Done, did not work, same error. Any other thoughts?

This is what my config looks like. I'm also using an older version of shopgui. I'm using 1.18.5 of shopgui.
Maybe this might help. Not sure. Hope you find a solution D:

        type: item
        item:
          mob: Chicken
          name: "&bChicken &7Spawner"
          spawner: true
          quantity: 1
        buyPrice: 50000
        sellPrice:
        slot: 2
      3:
        type: item
        item:
          mob: Pig
          name: "&bPig &7Spawner"
          spawner: true
          quantity: 1
        buyPrice: 75000
        sellPrice:
        slot: 3

It could possibly be the order you have the config also. Try to make it look like mine
