String help

[keen]

Ok, I'm working out a network tik-tak-toe game, and I am running into some issues.

I have it send the text:

##playermove 1 username

The person and I am using this:

$playername = StringMid ($sReceived, 15)
;MsgBox (0,"",$playername)
    $numm = StringMid ($sReceived, 13, 14)
;MsgBox (0,"",$numm)

to get the player name and the number (space) that he is moving to.

For some reason, this isnt working, any ideas as to why?
