Bizarre Conditional Formatting results

All,

I have an Excel sheet with three conditional formatting rules to enable easier reading of the data portrayed in the sheet but am getting unexpected results.

Rule 1:
=$D3<>$D4  
compares a task reference in column D and adds a border to the bottom cell when the task reference changes

Rule 2:
=$A3=1  
in column A I have the following formula:

=IF(B3="","",IF(D3=D2,A2,ABS(IF(A2="",A1,A2)-1)))

This alternates the value in column A between 1 and 0 based on the change of task reference in column D. This then formats a shade of green for the lines equal to 1.  The appearrance of the report is now green and white shading alternating with change in task reference.

Rule 3:
=AND($D3<>"",ISERROR(IFERROR(MATCH($D3,LoL!$E:$E,0),MATCH($D3,Enabling!$E:$E,0))))

Checks that the Task reference is included in the summary reports on other sheets, if not it highlights red.

Rules 1 & 3 seem to work fine. However rule 2 works but some rows end up with a different shade of green.

See attached screen shot.

Any suggestions??

Thanks

What happens if you change the green color (say to blue). Do you have this difference in colors then?

1 and 3 works becuase the result of the logical test, either is true or false or 1 or 0   which triggers the conditional formatting.

however, if you look are the 2 =IF(B3="","",IF(D3=D2,A2,ABS(IF(A2="",A1,A2)-1)))  

ABS(IF(A2="",A1,A2)-1))  this part would be fine, although i do not know the values of A1 and A2

IF(D3=D2,A2   would work fine if the A2 either hold 1 or 0   (you did not specify what value is in A2)

this one IF(B3="",""  this runs first if B3 is empty then will always return false if empty . because the return value is a null string empty and your rule 2 of =$A3=1  would return false.

That's the bizarre thing, when I copy and paste values and formats into a copy file with a view to taking out the sensitive data, the CF works fine. I end up with alternating red and green because the red rule takes over because it can't find the task reference elsewhere but the green rule works ok, alternate lines are the same shade of green.

If you look at the screen shot I uploaded, the paler shade of green is the correct shade and is what I get for all alternate blocks on the copy file.

Prof JJ - Rule 2 also gives TRUE or FALSE. The CF Formula is =$A3=1

The formula that you broke out is in cells in column A and that works fine, it alternates values 1 and 0 for alternating blocks based on the task reference in column D but allows for previous row being blank, shown on screen shot as left most column.

Philip - I tried with different colours and the same happened.

I tried removing Rule 2 and replacing but same result.

Thanks

Are the green ones getting red if you remove the task reference?
Seeing the screenshot the paler green seems to be wrong - the CF shows a darker one.

I think without the sample file (which only needs to contain columns A and D), we are a bit in the dark.

Hi All,

Thanks for your inputs but unfortunately I was not able to upload a sample file. As soon as I replicated in a sample file it worked fine.

So I decided to remove all CF, remove all manual cell fill formats and re-apply the CF. It now works fine.

Thanks
