Of course it is initialized as the fields are already defined in the page as an array. Your simply doing a foreach custom- array return results and the code is quite clear here. PhotoPost Classifieds - test
I am not seeing any issues and I tested every type of extra field there is
I would suggest you email support with enough urls and logins ftp etc database and explain your issue. If you change the code your not going to be able to save your array results.
