[HELP] Game doesn't realize i'm on round 100

[SoaR Voltz]

(completely new to all of this) I have got to where when I start you start on round 100, but you start with 231 zombies and not 924. it's exactly 1/4 the amount and don't understand why i'm not getting the right values.

#include maps_utility;
#include common_scripts\utility;

init()
{
level thread set_round();

}

set_round()
{
level.round_number = 100;
level.zombie_move_speed = level.round_number * level.zombie_vars["zombie_move_speed_multiplier"];
level.zombie_vars["zombie_spawn_delay"] = 0.08;

}
