Could you post the Perl code or template markup?

Mike T. Thanks,

I bolded the relevant text below:

here is my Comments template:

 <MTUnless name="comment_preview_template">
  <$MTInclude module="Comment Form"$>
  <br /><br /><hr />
 </MTUnless>

 <MTComments>

Comments

And here is the Comment Detail Template that is supposed to output the variable "expand" but always outputs the default "3" instead of the new SetVar value.

Sorry,, I don't know how to post the template html. It truncated in the previous comment. I will try again, removing the < and > 's .

All the template Xhtml works fine, except this one setvar function.

   mt:Var name="expand" value="3"

   mt:If tag="MTEntryCommentCount" gt"5"

    mt:Var name="expand" value="1"

   /mt:If

   mt:If tag="MTEntryCommentCount" lt"6"

    mt:Var name="expand" value="2"

   /mt:If

  MTCommentsHeader

   h2 class="comments-header" $MTEntryCommentCount$ Comments /h2 

   mt:Var name="expand"

   div class="comments-content"

  /MTCommentsHeader

Also, try using http://www.movabletype.org/documentation/appendices/tags/setvar.html instead of var
