On the form there are 4 pages of a page frame, 3 of which use the same two tables. On the second page there is a grid with a quantity column. The result of this quantity column is displayed on the third page. For example, if I add two records in the quantity colunm of the second page, these two records are displayed on the third page. If I then delete these same two records from the third page, the quantity is updated on the second page. If I then add 2 more records, the system crashes with error 109 as it is diplaying the 2 new records. I know that this scenario is somewhat far-fetched for a user to do, however, I do not want to field this application with this error occurring. Sorry for the "book" that I wrote. To answer your question, I don't think that I am nesting transactions. The tables are updated in the losfocus events of the cells.
