checkitem problem

[plush sequoia]

hello, i am trying to use this %checkitem_give_enchantments:sharpness=10;fire_aspect=5;unbreaking=10;looting=5;mending, mat:diamond_sword, amount: 1% , but i am getting an error saying invalid material.. but if i do the material before the enchantments it only gives me a plain sword.. any ideas?
