ROS脚本问题，求高手帮忙

我有一个二线的脚本，
:local assign-address
:local new-address
:local status
:local gateway1
:local gateway2
:local x
:set x 2
:for i from=1 to=$x do={
    :set status [/interface get [/interface find  name=("pppoe-out" . $i)] running]
    :if ($status=true) do={
     :set new-address [/ip address get [/ip address find dynamic=yes interface=("pppoe-out" . $i)] address]
     :set new-address [:pick $new-address 0 ([:len $new-address] -3)]
     :set assign-address [/ip address get [/ip address find dynamic=no interface=("pppoe-out" . $i)] address]
     :set assign-address [:pick $assign-address 0 ([:len $assign-address] -3)]
        :if ($assign-address != $new-address) do={ /ip address set [/ip address find comment=$i] address=$new-address network=$new-address broadcast=$new-address
        /ip route set [/ip route find comment=$i] gateway=$new-address
        /ip firewall nat set [/ip firewall nat find comment=$i] to-addresses=$new-address
        /ip route set [/ip route find comment=$i] gateway=$new-address

       :set ("gateway" . $i)  $new-address
       }
   }
}
gateway1,和gateway2分别是双线外网拔号得到的IP地址，想把这两个IP地址作为我的静态路由表里的网关，我用
/ip route set [/ip route find comment=all] gateway=$gateway1. "," $gateway2.怎么不行，这条语句应该怎么写啊，请高手帮忙
