Solved arg-2 mob spawner is not a type

[zaved]

if arg 1 is "withdraw":
            if arg 2 is a number:
                if {spawner.%player%} is more than 1:
                    remove arg-2 from {spawner.%player%}
                    add arg-2 mob spawner to player's inventory
                    stop
                else:
                    send "&6&lHydopia&c&lAMS &8» &cYou must have spawners in your &4AMS &cfor withdrawing them"
                    stop

Can someone explain me or help me why the add line doesnt work?

It should be like
- you have e.g. 100 spawners in your virtual mine
- you want to withdraw 10 spawners
- those spawners should be remove from players virtual mine
- he should get the amount of mob spawners in his inventory that he used as arg 2

append `of` to specify amounts, ex. `20 of dirt`
