Thanks,
I have managed to figure quite a bit of it out.
I copied the contact us structure from http://www.zen-cart.com/forum/showpo...27&postcount=9 and have renamed/edited the files to be 'trade_contact' instead of contact us.
I added new data input boxes to the form in tpl_trade_contact_default.php:
Code:
<label class="inputLabel" for="contactcompany"><?php echo ENTRY_COMPANY; ?></label>
<?php echo zen_draw_input_field('contactcompany', $company, ' size="40" id="contactcompany"') . '<span class="alert">' . ENTRY_REQUIRED_SYMBOL . '</span>'; ?>
<br class="clearBoth" />
and in trade_contact.php.
Code:
define('ENTRY_COMPANY', 'Company:');
However I can't get the new data fields to appear in the email which is sent from the form.
This is somewhere in header_php.php but I don't know what to change and where to add the new code.
Any ideas?

Kind Regards
