Terry workd fantastically well, thankyou.

Just out of interest on the article table and fabsum table.

The articles tables is supplied from our software vendor and I am basically bolting on the fabsum table with my own form. Therefore when invoking this program I want to enable buffering on the fabsum table. But I have noticed I dont have to use the tables when using the data environment. Therefore when do I set the buffering mode on and do I have to select fabsum first?

In addition to this am I right in saying that when I click on my save button I have to select fabsum first before tableupdate . The reason i say this is that when I run the form the currently selected table is articles and we cannot update this.
