I've been trying to figure this out and now I must ask the guru's of this board! :)

On the Check Out page I would like to change the "Order Comments" title. Where would I find this file to do that?

Also, we are getting customers calling us saying that the shipping part of the one page checkout is saying:

United Parcel Service
111210: The requested service is unavailable between the selected locations.
If you prefer to use ups as your shipping method, please contact...

If you click change address and then click continue with out actually changing the address, then the UPS will show rates for your zip code.

This is only happening with 1 out of 10 customers. Any thoughts?

Thanks
