How do I validate cloned form field inputs

How do I validate cloned form field inputs

Hello all, I'm having a bit of an issue using Validator plugin on Form Elements that get cloned.

At first, the form had a single "set" of numeric-input elements that had a distinct name and id.  The fields were "low value" and "high value". Validating that the "low" value was a 'number' and less in value than the "high value" element was simple and straightforward (and worked).

The requirements changed, driving the need for many 'levels' - so I changed the
"name" attribute for each, to that of an HTML array notation.

I used clone(true) on a live('click') function, but now it seems the validator does not work as expected, nor does it validate the clones at all - so apparently I'm doing something wrong or missing a step in the chain.

Please see the JS Fiddle at  http://jsfiddle.net/nylinuxhelp/dVLsr/48/

Any help would be appreciated, thanks.
