Hi, John
Ok .. the example with the get-parameter is quite good.
You'll often have the case that you submit a string "0" or "1" and
want to have it as boolean (f.e. if you have a dropdown with two
options).
Please keep in mind not to mix it up with checkboxes as unchecked
checkboxes won't be sent back to your webserver :)
Bye
Simon
