I need to Zero index $Pos as TwitterBootstrap Carousel complains if not!

http://getbootstrap.com/javascript/#carousel

Any idea how I would do this in a loop...

 <% loop SpinnerImages %>
    <li data-target="#homepageSpinner" data-slide-to="$Pos" class="<% if First %>active<% end_if %>"></li>
  <% end_loop %>

Thanks!

Try this:

data-slide-to="{$Pos(-1)}"

Very randomly that does...

<ol class="carousel-indicators">
    
    <li data-target="#homepageSpinner" data-slide-to="-1" class="active"></li>
    
    <li data-target="#homepageSpinner" data-slide-to="0" class=""></li>
    
  </ol>

Ah sorry, I was thinking that the iterator started at 1:
