Indeed we are only humans, and I have no idea on what you are refering to, since I told you exactly what you are telling me. The "fix" that you sent was : ====//==== try this : if (!($value="206.20.254.3")) { echo "\$var = $value<BR>"; } you must 'escape' the "$var" as it will think it is a variable not a string, and I have found that "!=" is unreliable ! richard ====//==== You see ? Only one "=" there means that you will be always assingning "206.20.254.3" to $value, instead of checking the equality using two equals "==", which is the correct way to go. But I can go even further, doing ( $value != "blah" ) and ( !($value == "blah") ) is the same thing, or at least is on my "reliable !=" operator :) Joao -- Joao Prado Maia Web Developer Kefta, Inc.
