if (say isin $gettok(%rcon.data,2,34)) {
      if ($gettok(%rcon.data,3,34) == !needsub) {
        if (!%ignore.admin) {
          %rcon.data = $nick1($gettok(%rcon.data,1,34)) $+ : $id($gettok(%rcon.data,1,34)) $gettok(%rcon.data,3-,34)
          rcon say Getting a substitute player from IRC
        }

I need an if statement to make sure that $id($gettok(%rcon.data,1,34)) matches a steamid from a text file
