I want to confirm on the second line that the player has the item and I have enough items on me, but it still judges it as not having it

I have confirmed that the contents of {_item} and the items in my backpack are "cobblestone block"

Code (Text):

1. function money(p: player, n: number, item: item, price: number):
2.     {_p} has {_n} of {_item}:  ←here
3.         remove {_n} of {_item} from {_p}
4.         add {_price} to money of {_p}
5.     else:
6.         send "you don't have enough items" to {_p}
7.         play sound "block.note_block.pling" with volume 2 and pitch 0.5 to {_p}
8. on inventory click:
9.     name of event-inventory is "menu":
10.         cancel event
11.         set {_item1} to type of event-item
12.         index of event-slot = 0:
13.             money(player, 1, {_item1}, 0.5)

 

Sorry, I forgot to change it, because I will change the code to be easier to read before publishing, now I edited it

 

Oh, it turns out that there are three ways, I read this to know, I have been using variables + inventory name, let me change my code to try

I replaced the GUI with metadata, but it still doesn't work.
Still output "you don't have enough items"
Or do you need the full .sk file?

 

I also changed a little to make it easier for you to read, thank you very much!

 

That's okay, but you solved this problem that has been bothering me for a long time, thank you very much for your help! (* >ω<)
