Weapons on deathrun in pointshop

Im trying to add melee weapons to my pointshop in Deathrun. I have a crowbar in there and it works fine but the minecraft sword doesnt. This is the code i have for it

ITEM.Name = 'Diamond Sword' // change this to whatever name you want
ITEM.Price = 1000 // change this to whatever price you want
ITEM.Model = 'models/weapons/w_diamond_mc_sword.mdl' // change this to what shop 'icon' you want
ITEM.WeaponClass = 'mc_sword_diamond' //change this to name for item you want to replace the crowbar with
ITEM.SingleUse = false // makes it persist every time. This does sometimes bug out, a good suggestion would be to add more weapons before this weapon that work similar, may give a workaround to your issue.

function ITEM:OnBuy(ply)

function ITEM:OnSell(ply)

You can buy it but it isnt in your hand. You still have nothing.

Can anyone help me figure out how to add these?

First of all, do you actually have a weapon called mc_sword_diamond?

When someone buys the item, is anything printed in console about missing/unknown entity?

I fixed it myself! Thanks guys!
