The AND function takes each of the conditions inside the brackets and evaluates for their truth, and then multiplies the results together. TRUE = 1 and FALSE = 0. So if any condition is FALSE then the overall statement returns FALSE.

The formula for AND needs to be placed in brackets with each of the conditions separated by a comma. For example =AND(H1<1,G1>1)

In this instance the function will evaluate H1 to see if the value is less than 1. if it is then it will return TRUE or 1 and if not FALSE or 0. Then it will do the same for G1.

The two values are multiplied together and the answer is then either 1 or 0, TRUE or FALSE.

The Excel Help says:

One common use for the

ANDfunction is to expand the usefulness of other functions that perform logical tests. For example, theIFfunction performs a logical test and then returns one value if the test evaluates to TRUE and another value if the test evaluates to FALSE. By using theANDfunction as theargument of thelogical_testIFfunction, you can test many different conditions instead of just one.

I received this question on the website from Eric regarding conditional formatting:

Hi,

I have the same problem as a few people above but I don't think you got the point of the problem,

In xl2003 if you select A3:A9 and enter conditional format =B3 then select any other cell in the range it will show the conditional format for that cell e.g. A7 will show =B7

In xl2007 after following the same steps it will apply the correct formatting but if you select cell A7 to view the conditional format it will show as =B3. You get the same when checking any cell in range A3:A9.

This makes it near impossible to edit or amend or debug conditional formatting once entered.

Any advice would be appreciated.

Eric.

I started to post my answer and realised that i would be better off writing the whole thing as a blog post with some images to explain.

Hi Eric

i understand the problem and the first answer is that you cannot apply the same sort of logic between the two versions. The new versions (including 2010) manage conditional formatting completely differently, though some of the same concepts apply.

First of all your conditional format formula should be =A3=B3. This will apply the conditional format when the cell in A3 contains the same value as the cell in B3, and this will be relative - eg. when A7=B7 the cell in A7 will have the format applied. So you can see that the relative approach is correct in the conditional format manager in Excel 2007/2010

Second the problem you mentioned. When you look at the relative formula in cell B7 in excel 2003 it showed you just that formula. that is actually harder to debug if you think about it in Excel 2003 than in 2007/2010 as there is no way to see what other cells it also applies to. In Excel 2007/2010 the conditional format manager allows you to see the formula - and the range it is applied to and the little range box (circled in the image below) allows you to view this

The manager allows you to confine the selection to be evaluated to the selected cell(s), the current worksheet or other worksheets in the same workbook. If you then understand the relative / absolute nature of the formula you created then you can debug very successfully. I actually preferred this once I got a hang of using the manager to create sets of conditional formats than can be applied to multiple ranges simultaneously.

I had a reader request some help with Conditional Formatting in Excel 2007.

Hi

Baffled in trying to get to grips with conditional formating in 2007

Scenario :

Column A = Actual Result

Column B = Target

Column C = Needs to show

1) If Actual result is less than 90% of target turn font colour RED

2) If Actual result is >90% of target and is <100% of target turn font colour AMBER

3) If Actual result is >= 100% of target turn font colour GREENIf column C meets criteria 1 use character "R", criteria 2 = "A" and criteria 3 = "G"

I can acheive 1 and 3 with =IF(a1b1,"G")) and then conditional format so that if contents of cell = R or G then colour font accordingly </B1,"R",IF(A1>

I`m stumped with the % factor and also think there might be a better way of doing it

Any help would be appreciated :)

Here is a solution to this problem.

We formatted two columns to give two examples as to how it could be done.

The actual column determines the percentage as part of the conditional format and formats in that way.

The result column formats on the “R”, “A”, and “G”.

The formula in Column C1 is =IF(A2/B2<1,IF(A2/B2<0.9,"R","A"),"G") and this can be copied down.

Here are the rules for Column A
