I have a spreadsheet that needs to hightlight some dates based on multiple
criteria and I cannot get the Formula in the Conditional Formatting function
to work.

A1 = date
A2 = date
A3 = date (not always present)

I want if =A3="" and A2<Now() show the text in A2 in Red.

I've also tried =A3<Date(2000,1,1),A2<Now()

Anyone have any ideas? TIA rasinc
