Thanks, but It needs to be,
IF THIS HTML -
<div class="nav_bottom"> </div>
</div>
<div id="login">
<div class="nav">
<div class="nav_main" style="min-height:35px;">
{if $login eq "" }
{include file="customer/auth.tpl" }
{else}
{include file="customer/authbox.tpl" }
{/if}
{include file="customer/news.tpl" }
{if $active_modules.XAffiliate && $config.XAffiliate.partner_register eq 'Y' && $config.XAffiliate.display_backoffice_link eq 'Y'}
{include file="partner/menu_affiliate.tpl" }
{/if}
{if $active_modules.Interneka}
{include file="modules/Interneka/menu_interneka.tpl" }
{/if}
{include file="poweredby.tpl" }
</div>
</div>
ELSE - 'Nothing'
as the style is shoming up unless this whole section is in the statement.
