Ok, got it working. You'll have to intercept the argument rather than the=
=20
session to make it work. This works for me:

<SURVEY TITLE=3D"Hello">

   <LICKERT NAME=3D"var1" CAPTION=3D"var1" />
   <LICKERT NAME=3D"var2" CAPTION=3D"var2" />
   <LICKERT NAME=3D"var3" CAPTION=3D"var3" />
   <LICKERT NAME=3D"var4" CAPTION=3D"var4" />

   <ROUTE CONTINUE=3D"{&

   $val =3D $argument->ArgByName("var1") || "novalue";

   if($val eq "novalue")
   {
     print "default.survey";
   }
   else
   {
     $val +=3D $argument->ArgByName("var2");
     $val +=3D $argument->ArgByName("var3");
     $val +=3D $argument->ArgByName("var4");

     if($val > 5)
     {
       print "morethan5.survey";
     }
     else
     {
       print "lessthan5.survey";
     }
   }

   &}" />

</SURVEY>

Reason for first part of if() statement is so document parses even when no=
=20
data has been submitted.

Hope this helps you.
