Zoom Script?

[Fysez]

I made a zoom script, And i know i'm not the only one who has.
But I did this, and it doesn't show up to others as enlarged?
I've tried different ways but the clientside makes it nearly impossible for me to work with.

PHP Code:

//#CLIENTSIDE
function onPlayerChats() {
if (player.chat.starts("/zoom ")) {
player.zoom = player.chat.substring(7).trim();
setzoomeffect this.zoom;
}
}
