empty var

[Anon]

I have a listens lrean http script. The user doesn't have to reply to each question. This produces a empty var and the minute I attempt access it or provide a filler before sending to the DB I receive and PHP error( undefined varable), if the user provides an answser the error doesn't ocur.

dont know if this is any help but did you initialise the variable

$info = "";

before your form refers to it? then maybe
if (isset($submit)){
if ($info == "" ){
$info = "Currently no information";
}
}
I maybe way off track here since I have only just tried to pick this stuff up...in which ignore all that you have read.
