Sorry, I should have looked at your code first. I guess I'm having
trouble understanding your problem then... If it's that $prodname isn't
being set in the global scope, you need to modify the $GLOBALS array
directly within your functions. So, instead of:

global $prodname;
$prodname = 'foo';


$GLOBALS['prodname'] = 'foo';

This goes for all those other variables ($tag, $insideproduct, etc.),
too. Also, you might want to consider using uppercase variable names to
distinguish global variables from local ones within your functions. It
would make your code a lot more readable. :)
