Allowing edits in a query based datasheet

[degras]

I have a datasheet that looks up data based on a query of two tables. The datasheet shows the data correctly, but it will not allow edits. I tried setting the data entry property to True but this had no effect. Also I was looking for the place where you can set the primary key for the form, but I could not find it. It would be good if edits were allowed on this form, is this possible?
