I tried both adding pipes, removing the quotes around the entire href and
both.  It doesn't seem to make any difference.
Here's what i tried:
----= Partial code block =-------------
<a href=[area href=scan
            arg=|
              fi=products
              st=db
              co=yes

              sf=category
              se=[catlist-data cat name]
              os=yes

              sf=prod_group
              se=[sql-param name]
              os=yes
            | interpolate=1] class="maintext">[catlist-data cat name]</a>
----= Partial code block =-------------
