Have you considered using "$Scratch->{somekey}" rather than
"$Scratch->{$somekey}"?  (Note the spurious '$' characters in
your code.)

Try this instead:

[calc]
    ($Scratch->{pstn2},$Scratch->{pstn3}) = (split('/',$Session->{last_url}))[2,3];
    undef;
[/calc]
pstn2 = [scratch pstn2]<br>
pstn3 = [scratch pstn3]<br>

Just like other examples, that one is untested.  You'll be wanting
to buy a Perl book soon. :-)
