How do I change the number of files to be uploaded?

[nuki]

Hi:

By deffect, there are 5 files to uploads, but I would like to be only 3. How can I change?

I've tried change upload.php:

// Some placeholders.
$customize = CUSTOMIZE_UPLOAD_FORM;
$user_form = USER_UPLOAD_FORM;
$allowed_URI_boxes = 3;
$allowed_file_boxes = 3;

...but thasn't work

Thanks

It's a setting on the groups page. No need to start editing code.
