I don't think it adds the tags with the same name because when I test the
params the first p_scnt comes through as the first value added. If the tags
were being added with the same name I would think that either 1) they would
be string with both values or 2) the last input would override the previous
input. Since param('p_scnt') equals the first value entered neither of
those outcomes are occurring.
