Glad to hear it, however just some critique of your coding style while
you're still learning. You should leave no doubt as to what variables
are for. Be descriptive, like:
$theObligatoryFieldFromTheFormTheOneThatMustBePresentAndContainAvalueMayInFactBePresentOrYouWouldReceiveAnE_NOTICEHoweverTheFieldContainsNoValue
= 1
Also look into isset() and empty().
