Description of problem:
This happens even when a '0' is entered properly in the form fields. Somehow, on
submission, the values are getting undefined and the checks are failing the
submission. If you set both to something like 1 or greater then it will pass and
submit any other changed.
Version-Release number of selected component (if applicable):
Incorrect return line in detaint_natural causing a value of 0 to be considered
invalid. Fixed now.
