i have been kind of messing around with this but not your exact problem.
Are you using a Template where the user will enter specific info
into specific cells?
what you might be able to do is create your template.
on the templete you could have a button.
When the user if finished filling out the data then the can
push the button, it would fire off a sub, which should be able
to grab all the data out of the cells and then build a query
string and then open that query string.
Now you should be able to grab all the values from the query string.
Can i ask what exaclty you are trying to do.
Because another option would be that once the user hits the button,
you could write back to your database or update your database with the info.
