OK, with 'ot_shipping' turned on with the same $ amount as in 'freeoptions' the add-on text does show in the shopping cart, but NOT in the sidebox. I have checked the location of all the over ride files, and I have checked the code of the tpl_cart_summary.php file, and everything seems to be correct.

If you are not running your shop in Australia and your 'ot_shipping' option is set to 'national' you need to change your /languages/english/extra definitions/[custom]/ free_shipping_qualifier_defines.php file to reflect your country.

I notice frank18 has not supported this for close to a year now. It would be nice if there were an indicator for whether add-ons are being actively supported or not, because it would make a big difference in choosing add-ons, at least for me anyway. Anyone know of another actively supported add-on that does what this claims to do?
