no problem, just an fyi to the original poster (if this helps at all)... you can do the following:
if (#channelname isin $aop($address(%nick,3)).type) {
if the entry exists and the channel name is in the .type it'll return true. If the entry doesnt even exist it'll return false. Also, I THINK (havent tried it yet) you could also do this:
if ($aop($address(%nick,3)).type == $null) {
to see if there is no channels listed there. Just some more ideas for you
