Need little help with a contribution

[biorgamix]

Hi, i installed a contribution which adds an entry for User and is located here http://addons.oscommerce.com/info/4816 , the entry name is RFC which is a key for the Mexican Taxes System that you are identified with. Is needed to make bills. In this contribution some files are modified and so far is good, but it has a little problem, for making RFC(new entry, field) to appear in Checkout address, user has to have Company field filled or Company has to be active as a value, which is not always that way, cause in Mexico any person can have an RFC, even when not part of a Company.

So in the file catalog/includes/functions/general.php

line 489 find:

if ( (ACCOUNT_COMPANY == 'true') && (tep_not_null($company)) ) {

$address = $company . $cr . $address;

}

change it to:

if ( (ACCOUNT_COMPANY == 'true') && (tep_not_null($company)) ) {

$address = $company . $cr . $rfc . $cr . $address;

}

So i was wondering how can i change it, for making RFC to appear, even when Company field is empty(null) or Company is disabled.

Any help will be apreciatted.

Thanks.

} else {
 $address = $rfc . $cr . $address;
