    It should say use a var_name in a var_loop, where "name" is not in "loop", but is a variable from elseware
      If I understand your question correctly, you're defining an HTML::Template parameter outside a loop and then trying to use it within a TMPL_LOOP. I.e., the code looks something like this:
      my $template = new HTML::Template ( filename => "file.tmpl" ); $template->param( outside_of_loop => "foo", the_loop => [ { inside_of_loop => "bar" }, { inside_of_loop => "baz" } ] );
      And your template looks like this:
      Outside: <TMPL_VAR NAME=outside_of_loop> <TMPL_LOOP NAME=the_loop> Inside: <TMPL_VAR NAME=outside_of_loop> <TMPL_VAR NAME=inside_of_l +oop> </TMPL_LOOP>
      You're expecting this output:
      Outside: foo Inside: foo bar Inside: foo baz
      But you're getting this instead:
      Outside: foo Inside: bar Inside: baz
      The problem is that TMPL_VARs defined outside of a loop don't show up within the loop. The solution is to set global_vars => 1 when you create the HTML::Template object. E.g.:
      my $template = new HTML::Template ( filename => "file.tmpl", global_vars => 1 );


      Read up in the documentation about setting your variables global.
