In my sample example I have a collection of members who are sorted by industry ( a text field) What I want to do is have a conditional header that is displayed when the industry group changes.

This is an outline of what I want to do.

      <div id="MemberList">
         <% control MemberList %>
            <% if $lastindustry <> $Industry %>
               <h2>$Industry</h2>
               $lastindustry = $Industry
            <% end_if %>
            <p>$Title - $CompanyName</p>
         <% end_control %>
      </div>

How best to achieve this?

the template parser is pretty basic in what you can do, eg you cant assign variables and change $lastIndustry inside the template.

What you would need to do is change your datamodel a bit for the template so you have a DataObjectSet of Industries. Then each industry has a DataObjectSet of Members so in the template you would do

<% control Industries %>
<h2>$Title</h2>
<% control IndustryMembers %>
$Title - $CompanyName
<% end_control %>
<% end_control %>

And so your PHP method Industries() would need to make a DataObjectSet of all the Industries then for each Industry generate a list of members for it
