What I have is I start off with the add_session_vars('blah'), then of
the first form, I have an input name="blah", which I make sure has a
value then I send the user form2.  On form2 I have an if "blah
=='value'" which works fine on the first run, but should that form2 be
displayed a second time I will get the error.  I was able to work around
this by add an input type="hidden" name="blah" to form2 so that blah was
always "submitted".

The above of adding a locals to set to None if it does not exist would
save me on a lot of redundant code; I'd only need to explictly state a
local if it was a list ( = [] ) or something simaliar.
