Module flow for create_account page?

[lat9]

I'm currently developing my site off-line:
Zen-cart v1.38a freshly installed w/ security mods
add-ons: FEC (most recent), product-extra-fields v1.2.1

I'm trying to figure out why some of the create-account form-checking isn't working correctly, and just want to get a sense of the program flow after the 'select' button is pressed on the form.

I'm guessing that the jscript_form_check.php file present in \includes\modules\pages\create_account gets run somewhere, but how does the control flow after that? There are a bunch of checks present in \includes\modules\<MYTEMPLATE>\create_account.php, but they don't seem to get run.

Thanks for any information ...

Never mind

The javascript runs on the 'client' and weeds out really stupid stuff before sending the form up to the 'server', where the actual create_account.php file gets run.

One of these years, I'll figure it out (maybe).
