RE: [PHP] isset()

If the result is always something, for instance in the worth case it is 'N/A' then do: if($AgeChild != 'N/A') you can continue isset check if the variable has at least a byte in it. so this will return true: $var = ' '; if(isset($var)) echo 'got something in it'; Just check for what you know is inside (or not inside) the variable.

Or should I use empty() ? Jack jacky@activelifestyle.com "There is nothing more rewarding than reaching the goal you set for yourself"
