Marc, best wishes to you in 1998 too!
I actually though about doing something like that but decided against it. The problem was data-validation. Since I'm using two field key for each line-item (for details please see my message to Barbara), I couldn't find an elegant way of doing validation using the grid for data entry. Please don't misunderstand my point. I do use methods similar to yours in other scenarios myself but I don't thinks it's appropriate for this purpose.

Thanks.
John.
