Well, im getting close. A few things:
-When trying to create the csv file in the /catalog/temp dir - dir didnt exist. I created one, set permissions temporarily to 777, and bang! It worked.
-Now when uploading the csv file, rather than the 'root' numbers of each category, it appears to want the actual name.
-Semicolons work best (at least in my case): WindowsXP users, Start-settings-control panel-Regional and Lanugage Options-Customize-list separator ;
-When adding a new product, it went to the correct category
-When updating an existing product, it changed it correctly, but also added a duplicate to the root of the catalog!
-Still having trouble with descriptions...going to try soon.
Thanks!
