    Hi Adam,

     

         The built in is working just fine. I'm now facing a REST API call issue.

     

         I'm trying to retrieve certain Community's blog list with

     

              <#assign global_blogsCount = rest('boards/style/blog/nested/count').value/>  

     

         However, when I try to use this value for a very simple calculation such as

     

              <#assign leftColumnEnd = (global_blogsCount/2) />

     

         I get the following error.

     

              Expression global_blogsCount is not numerical

     

         Could you please advice?

     

    Gracias,

    Luis

      As far as freemarker is concerned, the value you're getting back is a string. So if you want to use it as a number, you need to convert it. There's a "number" built-in that can be used with strings. For example:

       

      <#assign global_blogsCount = rest('boards/style/blog/nested/count').value?number />

       In case you're curious, you can find a full listing of the available freemarker built-ins here:

      http://freemarker.sourceforge.net/docs/ref_builtins.html

       

      I hope this helps!

        Thanks Adam,

         

             That worked out the issue. Could you please point out what's wrong on this snippet?

         

             <#if (global_blogsCount % 2) == 1)>

                  <#assign leftColumnEnd = (leftColumnEnd?int) + 1 />
             <#/if>
             <#list global_blogs.board?sort_by("title") as blog>
                  <#if gblogIdx != 0>
                       <#if (gblogIdx == (leftColumnEnd + 1) >
                            <#assign blogMenuContentAlpha = blogMenuContentAlpha + '</div><div class="hp-sub-nav-row blog-list-right">' />
                       <#/if>

                  </#if>
                   <#assign blogMenuContentAlpha = blogMenuContentAlpha + '<div class="hp-nav-col"><ul><li><a href="${blog.@view_href}">${blog.title}</a></li></ul></div>' /> <#assign gblogIdx = gblogIdx + 1 />
             </#list>

         

              Lines in bold are breaking my code

         

        Gracias,

        Luis
