Tell a Friend Button

[goosedesign]

Hello,

I'd really like to display 'Tell a Friend' just as a button, rather than the whole box etc. The code I'm using is

    <!--bof Tell a Friend button -->
    <?php
        
      echo '<a href="' . zen_href_link(FILENAME_TELL_A_FRIEND, zen_get_all_get_params(array('action', 'products_id')) . 'products_id='.(int)$_GET['products_id'].'&action=tell_a_friend') . '" style="float:left;">' . zen_image_submit(BUTTON_IMAGE_TELL_A_FRIEND , BUTTON_TELL_A_FRIEND_ALT) . '</a>'."\n"; 
    ?>
    <!--eof Tell a Friend button -->

It all displays fine, and works perfectly in Firefox and Safari on my mac, BUT, in IE6, clicking the button adds the product to the shopping cart instead. I can't understand the discrepancy, as surely it is server side code?!?

I actually had the same problem with the wish list module, although that also did it in Safari.

Any insights?
