Sorry Tore, I misstated the problem - there are no errors on the other hand it has no visible effect
I assumed the query table would open up to allow edit after the readwrite command.

>>>READWRITE makes the Email cursor (the result of the SELECT query) act like a table. You can add or delete rows, change the existing contents etc. If you don't include READWRITE the cursor is read-only.
