To me, that seems to be able to add several tags with the same id - I think that is harmful...

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.
No, you dealt with the names, but not with the ids. That's my only input so far. Isn't there a way to get param as a hash, so you could just use keys to get what you want?
