ScriptAlias /dancr "C:/Apache24/htdocs/dancr/public/dispatch.cgi" It all seems to boil down to the "my $flash;" global variable that never gets set correctly in "sub set_flash" (or read in get_flash)... I think it must be something about variable scope since the global and the subs are not part of a route in the context of the app...

Thank you for any input about this... I'm sure it's something obvious that I'm missing... but I'm hoping I can be enlightened...
