Can't use summon effect with coordinates

[slap_nap]

I was trying to use the summon effect but i cant i had code somthing like this:
every 2 seconds in "world":
spawn zombie named "&4&lZOMBIE" at [0 -28.92 57.00 174.06]

version: 2.2

i cant find understandable info on the syntax on any threads on skunity and before you ask i have looked on the documentation if somebody could just post the syntax that would be really helpful

this is my first post on skunity so please excuse any formatting errors

Try something similar to a teleport.

Examples:

every 2 seconds in world "world":
    spawn zombie named "&4&lZOMBIE" at location at -28.92, 57, 174.06 in world "world"
