The condition OR(Q9<"N/A",Q9<"n/a",Q9<"na",Q9<"NA") seems strange.
Isn't that always true, because it can't be equal to "N/A" and also equal to
"NA", so it has to be unequal to at least one of those? Note also that
those string tests are not case sensitive, so you don't need the pairs.

If you are querying the outer OR test, the best bet is to break it down into
manageable chunks.
Set up a cell with
=OR(AND(NOT(ISBLANK(Q9)),OR(Q9<"N/A",Q9<"n/a",Q9<"na",Q9<"NA"),(Q9+30)<=TODAY(),ISBLANK(S9) ),AND(NOT(ISBLANK(O9)),OR(Q9="N/A",Q9="n/a",Q9="na",Q9="NA"),(O9+30)<=TODAY(),ISBLANK(S9))) then a pair of cells with=AND(NOT(ISBLANK(Q9)),OR(Q9<"N/A",Q9<"n/a",Q9<"na",Q9<"NA"),(Q9+30)<=TODAY(),ISBLANK(S9) ) and=AND(NOT(ISBLANK(O9)),OR(Q9="N/A",Q9="n/a",Q9="na",Q9="NA"),(O9+30)<=TODAY(),ISBLANK(S9 )) respectively,and look at the TRUE or FALSE results from those.If you are struggling with one of those individual parts, then break thatdown again in a similar manner.If you are still struggling, then tell us what you have in Q9, S9, and O9,what result you are getting, and what you expected. Just saying "it doesnot work" doesn't help us to diagnose your problem.--David Biddulph"Ellen G" wrote in ... Thanks, Paul. I've tried rearranging the conditional formatting. Nothing solves the problem so far. What I am finding is that the OR statement inthe 3rd conditional format is simply not working. Even if I delete statements1 and 2 and it is the only conditional format statement, it does not work.If I use either piece of the OR statement by itself, it works. The ORcombination does not. HELP.

Ellen Typically I find that if the order of the conditions are changes toreflect the most likely condition first then the second then the third the conditional formating will work. Once a condition is met, in saycondition one, the program will no longer look at condition two and/or three.
