submit button at the top

Is there anything wrong with putting a submit button at the top of a form as well as on the bottom?

Will the top submit also submit the form?

As long as the submit button is still within the form and is set to the input type 'submit', yes it will still work the same.

From a usability point of view though, most people would expect the submit button at the bottom but I guess it depends on the layout and content of the page.

And do you use a reset button with your submit button? personally I hate reset buttons - I only ever click on them by mistake - and then they erase all my data. grr! That's useability
