I tried to apply this to 2.5 Classifieds (only the part recommended by Chuck), and it does not seem to work:

'extra6' => STRING, 'notify' => STRING,

Here is my code from uploadproduct.php:
'extra6' => STRING, 'notify' => STRING, 'highlight' => INT, 'bold' => INT, 'italic' => INT, 'keywords' => STRING, 'currency' => STRING, 'buyit' => STRING) );

Is there something else I should do? Is the other piece required as well?
Thank you,
