You are doing nothing wrong as such (Although some critics may claim its sloppy coding, which personally i think is trash!). All that it is, is that PHP is warning you that you are using a variable which does not have a value assigned to it. Since this is from a form page, the most likely problem is to do with 'Register Globals'.
When a form is submitted to a page, PHP takes the form details and creates the variables again. Rather than creating '$custname = value', PHP now puts all the values into a 'super-global array'. Basically, since your form uses post to send the details, your variable is created in your script as $_POST["custname"] $_POST is the post superglobal. It contains all the values which come to your script via a 'post' request. There are similar arrays for $_SESSION variables, $_GET variables, $_COOKIE variables and so on. If you have a problem finding out where your values have gone, a simple call to phpinfo(32); will show you all the variables in your script which you can access/use. You can also find more infomation on superglobals at: http://www.php.net/manual/en/security.registerglobals.php http://www.php.net/manual/en/language.variables.predefined.php#language.vari ables.superglobals To stop the notice coming up in the future (i.e. if you do want to use an empty variable for something) simply go to your php.ini and find error reporting. Changing error_reporting = E_ALL to error_reporting = E_ALL & ~E_NOTICE will stop those notices poping up in the future. Hope this answers your question.
