Solved Error Detecting Held Item Skript

[Chickenman]

Hi! I've been trying to create a mana skript for my server and I wanted an item to give you more mana. I created a command that did this, and it worked, but when I tried it with an item, it didn't. Here's my code:

variables:
    {max.%player%} = 20
    {mana.%player%} = {max.%player%}

every 1 second:
    loop all players:
        if {mana.%loop-player%} != {max.%loop-player%}:
            add 1 to {mana.%loop-player%}

every 2 ticks:
    loop all players:
        if loop-player is holding a stick in off-hand:
            {max.%loop-player%} = 25
        else:
            {max.%loop-player%} = 20
            if {mana.%loop-player%} > 20:
                {mana.%loop-player%} = 20
        send action bar with text "&bMana: %{mana.%loop-player%}%/%{max.%loop-player%}%" to loop-player

All I would like to know is the off-hand syntax for when I loop players. Thanks in advance!
