here's what I would do...
1) replace the type='submit' for the submit button with type='button'
2) add a function call to the button - onclick='javascript return
someFunction();'
3) in the function someFunction(), do your error trapping. if a condition
is met, do a form.submit(); else, alert the user then do a return false;
