R: Computing variables for routing

Hi all,

Again, it doesn't works;

The print instruction I've set at top of the  page reached:
print $session->getValue("SUBMITTED_sum") (sum is the new name of the
CONSTANT tag)
According the code below, always print 1 instead of the sum of
values.... :(
It seems that the instructions $session-setValue doesn't works into the
<submit> tag;
Again, the strange is that I've set value of 0 and not 1 in <CONSTANT>.

Ok, this is just me speculating a bit. I'll test in a more=20
structured manner tomorrow if this doesn't solve your problem.

How about a) making a CONSTANT variable in the page with the matrix, b)=20
use the submit-time perl to modify the value of the CONSTANT, and c) use

an IFROUTE to determine where to go based on the value of the constant?

(completely untested code: )

<SURVEY TITLE=3D"hello">

   <MATRIX ... >

   <CONSTANT NAME=3D"dummy" VALUE=3D"0" />

   <SUBMIT>
     {|
       $val =3D $session->getValue("SUBMITTED_var1");
       $val +=3D $session->getValue("SUBMITTED_var2");
       $session->setValue("SUBMITTED_dummy",$val);
     |}
   </SUBMIT>

   <IFROUTE DEFAULT=3D"page1.survey">
     <IF THEN=3D"page2.survey">
       <MORETHAN VARIABLE=3D"dummy" VALUE=3D"10" />
     </IF>
   </IFROUTE>

</SURVEY>

I'm not sure in which order the session is updated and the submit perl
is=20
run. This might fail because the session hasn't been updated, but if I=20
remember right it might work.
