Vlookup across sheets, nested Vlookup possibly?

[paid2mkgrlspanic]

I’m trying to develop a workbook which holds monthly data on loan information. It tracks the interest and balance on the loan. I want the first page to have a table displaying the interest payments for every individual tab. When I was brainstorming the idea, I was considering a sort of Vlookup function to find the tab the account is on and then a further function, possibly another vlookup which connects the month to that month’s interest payment. Can anyone help me figure this out?



The attached spreadsheet is obviously simplified, there are well over 30 tabs. But I would like it to, ideally, search the account number column, search the workbook for that account number, and then when on that page use the month at the top of the first page and retrieve the interest payment and put it back in the cell. It’d also be great if the formula can be transferred between workbooks. I’m not sure if that makes sense; basically if I were to copy that worksheet into the next months book, I would like that the formula read those tabs instead of becoming obsolete due to references from the first workbook.



I really hope that this is not to confusing, and any help will be very appreciated!
