Create a file called extrainfo.tpl in your skin1/customer/main/ directory.
Here is some sample code for your extrainfo.tpl file:
Code:
{ include file="location.tpl" last_location="Extra Info"}
{capture name=dialog}
{/capture}
{ include file="dialog.tpl" title="Extra Info" content=$smarty.capture.dialog extra="width=100%"}
Then go into skin1/customer/ and open the file home_main.tpl then insert these two lines of code
Code:
{elseif $smarty.get.mode eq "extra"}
{include file="customer/main/extrainfo.tpl"}
Then you can create a hyperlink as such
Code:
http://www.yoursite.com/yourlink/customer/home.php?mode=extra
