Find two items in inventory, get amount & remove amount. (LUA)

I want to create a command which would get two resources (sulfur & charcoal) then if player has X amount of both resources, then remove X amount sulfur & charcoal & gives X amount of gunpowder.

No clue how to do it tho.

Code:

PLUGIN.Title        = "First Plugin"
PLUGIN.Description  = "testplugin"
PLUGIN.Author       = "Unknown"
PLUGIN.Version      = V(1, 0, 0)function PLUGIN:Init()
    command.AddChatCommand("test", self.Object, "cmdCraftGunpowder")
endfunction PLUGIN:cmdCraftGunpowder(player, cmd, args)
    local findItem = player.inventory:FindItemID(1436001773);
    local amount = player.inventory:GetAmount(1436001773);
end

 

This is it in c#, if your line for amount works I dont see why this take line won't. But then again, I haven't done LUA
player.inventory.GetAmount(itemID); // Looks for the item in inventory and returns the amount
player.inventory.Take(null, itemID, amount); // Takes the amount of item

 

Sorry, yeah, I was trying to print the GetAmount, (tried with tonumber() and without tonumber())

How would I print the amount that I get?
