Passing Variables with PHP and MySQL

[Pat Sherrill]

I have an html page that reads a MySQL db and populates PHP variables.  I
have two forms within the html.  The tags in the 1st form are populated by
the database.  The variables are repopulated by using a javascript submit()
function when the user selects certain fields (accomplished with $PHP_SELF).
The second form collects other form data and its submit calls the next html
in sequence.  The form data is passed correctly in IE5 but not NS404.  What
is the most reliable/compatible way of establishing form data using PHP
variables from one form within a single html and passing it to the next form
in that html to ultimately be passed to a new html page (I am using GET).
TIA
