An alternative to this (if JavaScript is enabled) is to show a small
confirmation window where the user would be given a chance to review/confirm
what has been entered. This could be done for multiple fields all together
or for each field as the user leaves the field (with onBlur).

Incidentally, one of the problems with repeat fields is that some/many users
simply copy&paste from the previous field.
