Thanks Ulrich, but that is actually what i currently use (which doesn't 
work):

    <a href="whats this?"
        tal:attributes="href string:${here/message}?body=${item/body}"
        tal:content="item/subject">Subject
    </a>

The
>>tal:attributes="href here/message?string:?body=${item/body}"
was just me trying to think of another way to do it (which also doesn't work 
:/

In trying to figure out what was going on i threw in a
<b tal:content="here/REQUEST/body></b> just to make sure i was getting the 
variable, and indeed it displays the body variable first time around when 
the Search_Results PT is called, but when i use the previous or next links 
for the batch process, it seems to lose what it is. Is that just because of 
the here/REQUEST statement or has the variable actually been 'lost'
Here is the entire code, if it helps
Thanks for the support
Tim
