Your values did NOT disappear. You did not signalise that
submission of the form should be canceled (by returning false
from checkMoney), so the data was submited. You did not
specify "action" for "<form>", so the browser guessed that
it should submit data to the same address it was submited
from (different browsers may do different guessing, so you
should not ommit "action") this way showing you again the
same empty form.
