The data from the form does not come to the quiz block?

Question

Typesetting

The data from the form does not come to the quiz block. I didn't see any syntactic errors. Could you tell me what could be the problem and what is the best way to look for an error in such cases? The code editor does not see the error

Answer 1

look, this is the data being sent:
because you have a slider, then the slides are duplicated, and with them the fields, if the last fields are empty, then they come empty despite the fact that there are the same fields filled (with the exception of arrays)
plus the data you send here fort- boyard56.ru/contactform.php
and not in the quiz.php file
