Hello all, I'm using Numbers 08, and I'm trying to set up an invoice/hours tracker for my business. I'm trying to figure out if the following is possible: On one sheet I have a table with Date, Description, Hours and Invoice # as column headers. Each day's work is recorded, and an invoice # assigned for dates falling within each billing cycle. This part is done manually, and that's fine. On a second sheet I have an invoice to send to the customer. What I would like to do is input the invoice # in a cell at the top of the form, and have a table below self-populate with all of the relevant data from matching entries on the first sheet. The list would need to be of a flexible length, since some invoices may have more or less entries than others... Any help would be greatly appreciated! Thanks!
