Alright. Still not working as intended unfortunately, but I'm willing to guess I messed up somewhere since I've never tried using attributes like this.
PHP Code:
//Serverside, function onCreated()...
this.attr[0] = this.text;
//#CLIENTSIDE
text = format("<font size = 16> %s lolol</font>", thiso.attr[0]);
Before we tear apart the format part, let it be known that when setting player.chat to this.attr[0], it is still coming up null.
