Need help with the following –

1. I have 12 sheets, 1 per each month (Jan, Feb, Mar, and so on)
2. Each of these 12 tabs has different data, based on the month
3. A unique sheet (let’s say Program1) will retrieve data from Jan sheet. Once month of Jan is over, than this same sheet will need to retrieve data from Feb sheet (and so on throughout the year).
4. The location of the cells will be static, but the source of the data will be dynamic.

I was thinking that maybe a “trigger” in a master sheet would dictate when the Program1 sheet will know if to look for the data in Jan, Feb, Mar, and so on. For example, I would have a cell with number 1 in the Master sheet. When the cell has this number, the Program1 sheet formulas know to retrieve from Jan sheet. If it has a 2, retrieve from Feb sheet, and so on.

Is this possible? If so, how? Thanks.
