Solved Using a variable in a set slot

[SkRATZ]

Im trying to figure out how to use a variable instead of a number. Heres a piece of my code:

        format gui slot 15 of player with book named "&cShop" to run:
            close player's inventory
            open virtual chest with size 3 named "&cShop" to player
            format gui slot 9 of player with ender pearl named "&cEnder Pearls" to run:
                if {enderpearls.%player%} is greater than 10:
                    send "&cYou may only purchase 10 of this item"
                    set {enderpearls.%player%} to 10
                    stop
#                set {_ender} to "{enderpearls.%player%} ender pearls"
#                set slot 4 of player to {_ender} named "&cEnder Pearls"
                send "%{enderpearls.%player%}%"
            format gui slot 12 of player with slime block named "&cSlime Launcher"

Use {_var} of ender pearl

format gui slot 15 of player with book named "&cShop" to run:
    close player's inventory
    open virtual chest with size 3 named "&cShop" to player
    format gui slot 9 of player with ender pearl named "&cEnder Pearls" to run:
        {enderpearls.%player%} > 10:
            send "&cYou may only purchase 10 of this item"
            set {enderpearls.%player%} to 10
        else:
            set slot 4 of player to {enderpearls.%player%} of ender pearls named "&cEnder Pearls"
        send "%{enderpearls.%player%}%"
    format gui slot 12 of player with slime block named "&cSlime Launcher"

Here you go, @SkRATZ, this should work
