[Javascript] multiple onSubmit events not working

[Mike Dougherty]

what happens if you do: onsubmit=" return ( function1() && function2() & function3() ); "

If any of the functions return false, the form will not submit - it wouldn't be very friendly if 
each function reported problems...

It would probably be much nicer to have a handler function that called each subroutine and reacted 
appropriately for the return; so if function1() returns false, to not call function2() or 
function3()
