Ok, I'm trying to use a script, I put the file in the right place, I start up mIRC and connect, I go to a channel and I join it, I then try to type in the command at the status window to activate the script, it then says ****Your not on a channel
I don't understand, I joined a channel, but it says I haven't, what's going on?

did you put a "/" in front of the command?

like
/whois
/kick

Either what GTS said or you are running a script what sends text to a channel, if that is the case you must either nominate the channel in the script or be facing the channel while running the script.
