I figured out why I was getting the error (I had a space instead of _). Thanks to Jason for helping me understand where the error was coming from and how to test it.
I also now better understand Exporting and Importing a database using phpMyAdmin, thanks to Guy for guidance on that.
I resorted to going back to the beginning of the eCart getting Started Guide, and your answers and the guide were a big help.
However I am stuck on page 28 where it tells me to -
1.From the Files panel, open the music page for your server model (music.asp, music.cfm or music.php). (music.php DONE)
2.Choose Window > Server Behaviors.(DONE)
3.In the Server Behaviors panel, double-click the Recordset (rsItems) entry.
(In my Server Behaviors Panels I see no Recordset (rsItems). Only eCart Object (BlueSkyCart) and six eCart Add to Cart (BlueSkyCart).
I am going to skip this for now and continue on, but it seems important and I would like to know about it if I need to.
