I am trying to create an invoice using "Numbers 09" (iWork). I have sheet 1 which is the invoice template and sheet 2 which is a list of all my clients. So, in sheet 2, row 1 is a header. A2 = Client id, B2 is the clients name, and C2 is the first line of the address. D2,E2,F2 & G2 is the rest of the address including the postcode etc. In sheet one, on the invoice I have a cell called "Client id" and I would like populate the name and address cells based on what is inserted here. So Client id 1 would use the info in the row associated with it in sheet 2. Any help you can give would be much appreciated. email me at scottwchristie @hotmail.com and i can send a screen shot if this would help. Sorry, I said excel in the question but I am using Numbers 09 for Mac.
