Forums Scripts & Popups on input

ok i have no idea on how to do this if i say something like lol and then when it is sent my script will change it and it would come out LO L or something like that any one know i have been asking around for days -.-

On 1:INPUT:#:{
if ($1 == lol) { msg $active $replace($1,LO L) | halt }
}
