Thanks for your reply, but this is a toolbar that I'm happily familiar with.
I was talking about a situation where I would have a in the column 'change' in the example you provided, instead of -100 etc, a combo box for each row.
Or, broadly speaking, have more than one value for one record in a column without duplicating the record.
I.E Lisa will have -10 dollars, +12 Euro, and 15 surprisingly expensive Shekels :-)
