There are entries that $response$i $j{creden} don't have following {uName}; hence i am getting the error. I would like to check if $response$i $j{creden} key having the value {uName}; or not to verify a check before assign the value to a new variable. Any help is appriciated.	[reply]

`exists` is your friend. you need to test for existence of both `{creden}` and `{creden}{uName}` in an `if` condition Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

The "creden" value is null like the following "creden": null, and other one is the following "creden": { "uName": "5xxxxxxx" }, set the below condition for them and it works! `if ($response[$i][$j]{creden} ne "" ) { $responsuname = $responsetextall[$i][$j]{creden}{uName +}; } else { $responsuname = "No UNAME"; }` [download]	[reply] [d/l]
