Help .. A question about if then

Please be gentile ... I am new at this ror thing
I have a view which looks like this

<h1>Nicaragua Stamps</h1>

<table id ="stamps">
  <tr>
    <th>Scott</th>
    <th>Maxwell</th>
    <th>Description</th>
    <th>Url</th>
    <th>Mint</th>
    <th>Used</th>
  </tr>

<% @stamps.each do |stamp| %>
  <tr class="alt">
    <td><%=h stamp.Scott %></td>
    <td><%=h stamp.Maxwell %></td>
    <td><%=h stamp.Description %></td>
    <td><%=h stamp.url %></td>

    <td>

      <% if stamp.Mint == true %>
        <img src="/images/yes.gif" alt = "yes"/>
        <%else%>
        <img src="/images/no.gif" alt = "no"/>
      <%end%>

    </td>

     <td>

      <% if stamp.Mint == true %>
        <img src="/images/yes.gif" alt = "yes"/>
        <%else %>
        <img src="/images/no.gif" alt = "no"/>
      <%end%>

    </td>
    <td><%= link_to 'Show', stamp %></td>
    <td><%= link_to 'Edit', edit_stamp_path(stamp) %></td>
    <td><%= link_to 'Destroy', stamp, :confirm => 'Are you
sure?', :method => :delete %></td>
  </tr>
<% end %>
</table>

<br />

<%= link_to 'New stamp', new_stamp_path %>

When the if statement is executed the first time it seems ok but on
the subsequent times it shows only true.
I hope this makes sense ...

      <% if stamp.Mint == true %>
        <img src="/images/yes.gif" alt = "yes"/>
        <%else%>
        <img src="/images/no.gif" alt = "no"/>
      <%end%>
    </td>
     <td>
      <% if stamp.Mint == true %>
        <img src="/images/yes.gif" alt = "yes"/>
        <%else %>
        <img src="/images/no.gif" alt = "no"/>
      <%end%>

Well, you should invert the logic for your second case, if Mint is true,
then Used column should show No, no?

Was that your question?
