Avoid Echo looping

[ngethe]

I get a number of messages reply sent very many times
below is the code that I think should be taking care of this
but I get the error PHP Notice: Undefined index: message in /var/www/html/fbb/index.php on line 64 (where the below code is)
// skip the echo of my own messages
if (($message['message']['is_echo'] == "true")) {
continue;
}
