I'm referencing a cell in another worksheet in my workbook, but I want to be
able to define which sheet is referenced in the formula by choosing the sheet
name from another cell. Let's say cell A1 in Sheet1 of the workbook has the
value "Sheet 2" and I want cell A2 in Sheet 1 to reference cell B15 in Sheet
2. Instead of my formula being ='Sheet 2'!B15, I would like the sheet name
to be a separate reference. In other words, I want the formula to be:
='[reference Sheet 1 cell A1 to get the tab name]'!B15.

This way I can create a list with a dropdown box, and change the sheet name
to bring up numbers from different, identically formatted, sheets.

Anyone know how to do this?
