newbie with another HTML/navigation question

I have a php script that is invoked on 2 different occasions:

1) the first to create a page with a form the user will use to input 
information for a new table row - this form has method=POST

2) the script is run a second time to accept the input from the 
completed form, add the new row to the table on the database, then 
create a simple form with an "OK" button the user will click on to go to 
another page to view the result of the database maintenance - this form 
has method=GET

Everything is working great EXCEPT THAT the url parameter I attempt to 
pass on the second form to the php script that displays the database 
maintenance never gets there!  It's on the second form (<form 
method="get" action="bloglist.php?thread=yet%20another%20new%20thread">) 
but the bloglist.php script doesn't receive it.  The query string is 
empty when bloglist.php starts.

Also, another very curious, and perhaps revealing, thing - when I 
attempt to view the page source of the second form I mention above, the 
one with method=GET, I get the odd, and absolutely nonsensical, message 
"The page you are trying to view contains POSTDATA that has expired from 
the cache."  But this makes no sense, since this second page (with 
method=GET) has (or should have) no POSTDATA!?!

Can anyone make any sense of any of this for me?  I'm making pretty good 
progress in general, but, once again, I seem to have hit a snag here I'm 
don't seem to be able to get past.

Thanks for any help you can give me.
