[ic] Any way to get referring page?

[interchange-users@interchange.redhat.com (Tim Nelson)]

I have a page that is called from several other
pages via a link and I want the new page to
be able to generate a link back to the referring
page. There is probably a simple way to 
accomplish this but I can't see it.

The referring page creates a link like:
[set SetPage]
[perl]
$Scratch->{mynextpage} = "status";
return '';
[/perl]
[/set]

[page form="mv_nextpage=selectjob
    mv_click=SetPage
    mv_action=process
    mv_todo=return"] Select a different job? </A>

The selectjob.html page that I want to creates
a link back via:

[page form="mv_nextpage=[scratchd mynextpage]
     mv_action=process
     mv_todo=return"]

I CAN see that [page] doesn't interpolate
[scratchd mynextpage].

Any hints?
Thanks.
