Why would someone have "0" lines if typing "!ustats" can count as a line itself? Have it inc the persons line before typing it, that way if they are checking their own lines it will give them that line as well.

Look's like a good script.. I would possibly do it in this way and make it one on *:TEXT: event

on *:TEXT:*:#: {
  if ($1 == !ustats) {
    if (!$2) { msg $chan $+($nick,:) You have written $iif(!%lines- [ $+ [ $nick ] ],0,%lines- [ $+ [ $nick ] ]) line(s). }
    else {
      msg $chan $+($nick,:) $2 has written $iif(!%lines- [ $+ [ $2 ] ],0,%lines- [ $+ [ $2 ] ]) line(s).
    }
  }
  else {
    inc %lines- [ $+ [ $nick ] ]
  }
}

NOTE: This is untested.. Just thrown together.

Good script.

here:

on *:text:!ustats*:#: {
if (%lines- [ $+ [ $2 ] ] != $null) {
    msg $chan $nick $+ : $2 Has Writen %lines- [ $+ [ $2 ] ] lines.
}
else {
    msg $chan $2 Has Writen 0 Lines
}
}

Could be:

on *:text:!ustats*:#: {
    msg $chan $nick $+ : $2 Has Writen $iif(!%lines- [ $+ [ $2 ] ],0,%lines- [ $+ [ $2
] ]) line(s).
}

That would return 0 if the variable is $null :)

Thanks...

Am gonna grab this...

You can use

/inc %lines

in place of the $calc() to increase the count.
