Why isn't Template Toolkit aggregating my counter?

Question

I'm working on a simple Dancer app to log books a person has read, but in my template to show how many books a person has read, I'm stumbling into an error. I'm trying to go through ever row in the table of reading instances and add 1 to a counter if the reader is the same as the listed person.

Here's the code for the template:

<ul class="people">
<% IF people.size %>
  <% FOREACH id IN people.keys.nsort %>
    <li><h2 style="display: inline;"><% people.$id.name %></h2><br />
    Born <% people.$id.birthday %><br />
    <% FOREACH reader IN readings.keys.nsort %>
      <% count = 0 %>
      <% IF readings.$reader.person_id == people.$id.id %>
        <% count = count + 1 %>
      <% END %>
    <% END %>
    <% count %>
  <% END %>
<% ELSE %>
  <li><em>Unbelievable.  No people here so far</em>
<% END %>
</ul>

However, when I display it, count is only 1. Does anybody know what I'm doing wrong, or do you need more code?

Thanks.

Looks like you need to pull the count initialization out of the FOREACH reader loop:

<% FOREACH id IN people.keys.nsort %>
  <li><h2 style="display: inline;"><% people.$id.name %></h2><br />
  Born <% people.$id.birthday %><br />
  <% count = 0 %>
  <% FOREACH reader IN readings.keys.nsort %>
    <% IF readings.$reader.person_id == people.$id.id %>
      <% count = count + 1 %>
    <% END %>
  <% END %>
  <% count %>
<% END %>
