If that's all it has (and the channel name is the item name), you can just do:
on *:text:!tellme *:#: {
if ($hget(chans,$2) != $null) {
msg $chan item= $+ $2 data= $+ $hget(chans,$2)
}
else msg $chan No data on $2 $+ .
}
No need to even use $hfind since you can pull the item name directly because you are typing the full channel name.
Again, this assumes you have it set like you said... item=#channel, data=nicks. To have added it this way, you'd have used something like /hadd chans $chan nick
If, on the other hand, your channel ISN'T the item and you used a number for your items and the channel is just the first part of the data, we'd need to do something else. If that's the case, just let us know.
