Thank you for the help.
I'm guessing that the code I'm supposed to change for the home page is:
<div id="s5_homepage"></div>
<div class="s5_padding" onclick="javascript:bookmarksite('Shape 5 - City Portal', '<?php echo $LiveSiteUrl;?>')" >Make My Homepage</div>
I tried changing 'Shape 5 - City Portal' to 'Test Site' and I get error messages that it didn't save or fatal error. Am I in the wrong place?
Thanks again for your help.
