Help With Recipes

I was trying to make a data pack (for 1.21.3) that changes some vanilla recipes but i couldn't get it to work, I Placed a json file with this in it located in ExpensiveProgress(My pack) > Data > Minecraft > Recipe > Iron(a folder i added) { "type": "crafting_shaped", "pattern": [ "XXX", " S ", " S " ], "key": { "X": { "item": "minecraft:iron_block" }, "S": { "item": "minecraft:stick" }
}, "result": { "id": "minecraft:iron_pickaxe" } } Did i make an obvious mistake or is more info needed
