Just try to change below:

public zv_fw_class_zombie_select_pre(id, classid) {
    if (classid == g_ZombieClassID) {
        if (zp_get_user_flags(id) == 0) {
            zp_class_zombie_menu_text_add("*VIP* only!")
            return ZP_CLASS_NOT_AVAILABLE;
        }
        else {
            zp_class_zombie_menu_text_add("*VIP*")
            return ZP_CLASS_AVAILABLE;
        }
    }
    return ZP_CLASS_AVAILABLE;
}

-->

public zv_fw_class_zombie_select_pre(id, classid) 
{
    if (classid == g_ZombieClassID) 
    {
        if(zv_get_user_flags(id)) 
        {
            zp_class_zombie_menu_text_add("*VIP* only!")
            return ZP_CLASS_NOT_AVAILABLE;
        }
        else 
        {
            zp_class_zombie_menu_text_add("*VIP*")
            return ZP_CLASS_AVAILABLE;
        }
    }
    
    return ZP_CLASS_AVAILABLE;
}
