I am trying to make a workbook consisting of 3 pages. The third page will be basically a "data dump," specifically a list of dates.
Can I use one of the LOOKUP, INDEX, or MATCH functions to cause the behaviour of the first two sheets' formulas to change? A bit more detail...
Page one and page two of the workbook are calculators. A start number is entered, a list of variables is entered, and dependant on the variables entered, a set of calculations are performed on the starting number and a result is returned.
What I would like to do is to be able to enter a date on one of these calculation pages, have Excel look for this date on the "Data Dump" page, and use different calculations depending on whether the date appears on the list or not. Am I asking too much of regular formulas, or can I nest some functions to make this happen?
