Hi, fox.
Welcome to PHPBuilder.com.
It would help us to see your PHP script, so we can see what you are trying to do, and the context it is being used in.
The notice you are getting is that you are trying to use a variable that has not been set. You can test for this:
<?php
// test to see if variable is set
if(isset($variable))
{
echo 'The assigned value of $variable is: <b>' . $variable . '</b>';
}
else {
echo 'The variable, $variable, has not been assigned a value yet.';
}
?>
Check out the isset() function in the manual.
Hope this helps.
