I just upload a new version of "KC s2M Pro-rates", with main updates as follows:
- "sum" type works (finally...)
- supports multioption shortcodes (remember to set "shortcode text")
- allows to change ccaps (needs both old and new ccap's sets to have his rows in price plan's table)
Also there is some bugfixes and better admin input control, so it's good everyone to update.
