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
