Excel 2010 Conditional formatting. Highlings a cell if it contaons 1 of 2 conditions

Question

I am trying to highlight a cell (or possibly the entire row) if a cell contains a value less than 0 or #N/A. Either condition would invoke a bold red text with default background color (white).

Columns are:

Column A Column K Column L Column M Column N Column O File 1 File 1 File 2 Miles File 3
Equip # Ending Odometer Ending Odometer Driven Gallons Fuel MPG (Key) (Calculated) (Calculated) =Kn - Ln =Mn / Nn (Where lower case n indicates row number)

File 1 is the master file and I use VLOOKUP to include data from files 2 and 3, so File 2 Ending Odometer and File 3 Gallons Fuel may have #N/A or 0. Either calculated field may contain 0 or #N/A. If the VLOOKUP used in Columns L or N does not find a match with the value in Column A, #N/A is displayed.

I apologize if all this background information has confused anyone.

My question is how can I set a Conditional Background for values in columns L, M, N or O if the value in Ln or Mn or Nn or On is less than 0 or the value in Ln or Mn or Nn or On is #N/A.

One other thing, I know nothing about VBA or macros, so if your solution involves either, you will have to include all coding, etc.

Thank you for your assistance.

Answer 1

Disregard my comment to your question, this should do what you want. Create 4 new conditional formatting rules and select the "Use a formula to determine which cells to format" options. Use the following formulas:

    =IF(ISERROR($L1),TRUE,IF($L1<0,TRUE))
    =IF(ISERROR($M1),TRUE,IF($M1<0,TRUE))
    =IF(ISERROR($N1),TRUE,IF($N1<0,TRUE))
    =IF(ISERROR($O1),TRUE,IF($O1<0,TRUE))

Make them all apply to $L:$O and check the "Stop If True" box. This will highlight the entire row for you.

You can do this with a single condition, i.e.

=IF(COUNTIF($L1:$O1,NA()),1,IF(COUNTIF($L1:$O1,"<0"),1))
