Functions and communicating with the console

The issue is that I need to send a message to the console if the one sending it was the console. There are no errors in the code, it just doesn't work. It stopped working when I tried to implement functions instead of repeating the same code over and over

Partial Code (I am working through SSH, I can't copy, and I don't feel like typing everything):

command /itemkiller:
    trigger:
        set ({itemkiller} to toggle({itemkiller}, "ItemKiller", player)
function toggle(a: number, b: text, c: player) :: number :
    if {_a} is 1:
        message kiuimsg("Turned %{_b}% off")
        return 0
        exit trigger
    if {_a} is 0:
        message kiuimsg("Turned %{_b}% on")
        return 1
        exit trigger
    else:
        message kiuimsg("Sorry there must have been an error!")
function kiuimsg(a: text) :: text:
    return "<gray>[<pink>Kiui Moderation<gray>] <reset>%{_a}%"
