Here is a sample form. If you click the submit button, it will send the results to me in name/value pairs. The name is taken from the name argument in the tokens. The value is usually the input value.
With check boxes, the value is one of the arguments and it is only sent when the box is checked. For radio buttons, the value of the selected radio button is sent.
Copy the html, change the mailto to your address, fill out the form and submit it. What you get is hard to read but it can be figured out.
