I have tested them both and it seems that if I write hey/how r u/how are you they both work fine but then I use question/exclamation marks, they do not work. I tried editing the script but then it started working double >_< Anyone know what may be wrong?

Another question about the auto-scripts. Do my own messages trigger it in conversations with more than 2 people? It just happened and one simple brb resulted in 16 cyas from me >_>
*still waiting for an answer to my previous q*

Well without the script and how you changed it we can't really help you. I'm not sure, but maybe in a conversation with 2 people the origin doesn't work properly... I think I remember reading something about that but don't take it as gospel truth.

And as for the ? and ! If the script was edited, it should be able to filter them out. Not sure how though Probably involves using regexp which is totally incomprehensible to me at the moment

Cloudy

if(origin != Messenger.MyName)
{
//do the stuff
}

As for the punctuation well I dunno the code or how it does it, but something like
message.match(/^hey\b/i) or something like that should do a check for hey with punctuation.

The reason the script is messing up is unfortunately because it is badly coded. I think you'd be better off making a request for a person who's capable of programming to create one which works properly.
