Skull skin in custom inventory

command /staff:
     trigger:
         format slot 11 of event-player with couger44's head named "&4&lADMIN&c couger44" with lore "&4Administrador de &6&lMine&2&lTerra" to be unstealable

I try using "couger44's skull" but create this error:

Skript doesn't what "couger44" is, you have to parse it as an offline player like this:

"couger44" parsed as offline player #you can save this on a variable or use it directly

And use the skull expression for get the skull of that player
