I have a spreadsheet with two tabs Sheet1 and Sheet2. Sheet 1 has data in the
cells. Sheet2 has formulas in the cells that reference Sheet1. In Sheet2
there are 1,000 rows and 40 columns. The problem is I have cells that are
missing formulas in them. How do I create a function that will highlight the
cells that are missing formulas. I tried playing with conditional format and
failed.

Thanks in advance.
