Shawn,

>1. What 'SHOULD' the Add button on MMMaintenance form do ? Does it ,in VFP terms, append a Blank to the Dataset and then 'land' you on the new record fo data entry.

That's right...I recommend checking out the MM .NET sample application to see how it works (check out the MM .NET Dev Guide topic "The Sample Applications" for details).

>2. What SHOULD the Save button do. I assume it takes the amended Dataset and backupdates the Table

That's right

>Am I right here or is there additional code I have to insert , to get this functionality ? (I know there will be data checking and validation but lets forget about that for the time being)

All the steps you need to take are outlined in the MM .NET Dev Guide topic "Creating a Maintenance Form". I recommend checking out this topic to see if you've got all your code and settings in place.

Regards,
