I have column O which is date format 00/00/0000, column Q which has either the word 'Date' or a numerical figure to 1 decimal place and column I which has a numerical figure to 1 decimal place. I need a formula in column S that looks at Q and if it shows date then it needs to return N/A in the S cell and if it has the numerical figure to 1 decimal place it needs to do the sum Q-I and give the result in the S cell. What should my formula be? Thanks in advance for any help. :-)
