Problems with composing e-mail parts using custom code

Im making an email with is supposed to include some form info, but only if certain checkbox is checked (fakturatak). If so then depending on a radio button option checked (fakturaktoredane) a part of the email (danedofaktury) is composed. However when I put {danedofaktury} in the email template I just got an "empty" mail

<?php

if ('fakturatak' == 1) {
	
	if ('fakturaktoredane' == 'stare') {
		
		
$form->data['danedofaktury'] = "{$form->data['nazwisko']} {$form->data['imie']}, {$form->data['nazwafirmy']}
{$form->data['kodpocztowy']}, {$form->data['miejscowosc']}, {$form->data['ulica']} {$form->data['nrdomu']} {$form->data['nrlokalu']}";


	} else {
		
$form->data['danedofaktury'] = "{$form->data['fakturanazwafirmy']}
{$form->data['fakturaadres']}
{$form->data['fakturanip']}";

		
	}
	
	
} else {
	
	$form->data['danedofaktury'] = "empty";
	}




?>

Im new to PHP coding so I only know that I set up my custom code wrong. How to fix it, I have no idea though.

Hi taro8,

Please check your PHP. This check will always fail

if ('fakturatak' == 1) {,

I think that you need

if ( $form->data['fakturatak'] == 1 ) {

and the same in the rest of your code.

Unfortunately with your suggested changes I get " Undefined index" error now, the check still fails.

I had the feeling it was just spelling error. Solved.
