I did not misunderstood because i read it carefully and you only explain how is working but i know how is working the point here is when the $did is 0 (when i click somewhere that there is not any ID exists) and the $did(0).text is $null to return $null instead of error message that is only my suggestion/bug report in this case and nothing else more, if you look further about it you can understand why to return $null instead of error message, in my first example i use an variable to store the currently $did text but i got error message that it should not get it but only gets back an $null because the most identifiers of the mIRC when there is not any data to return its getting back and $null and not an error message.
