Conditional formatting

[Tahir]

Hi
I have two columns say A & B
col A contains Student Name and col B Father name.
I want to highlight Student name when it occurs more than once in col A.
And highlight Father name only when it occurs more than once but when it also have same Student name in col A appeared more than once.

aa ff1
bb ff2
cc ff3
bb ff4
dd ff5
cc ff6
bb ff2

The last entry should only be highlighted as both bb & ff2 already appear against each other.
hope this explains my problem.

Thank you.

Hi

Referring to your stated crieteria, in column A where you have several student names that are the same (ie bb appears 3 times, cc appears twice) - do you want all instances of these highlighted by the conditional formatting, or only the second/thir instance?

Select columns A and B and apply this formula in conditional formatting

=(SUM(IF($A$1:$A1&"-"&$B$1:$B1=$A1:$A1&"-"&$B1:$B1,1))>1)*($A1<>"")

Hi

Thank you for the formula. Can you please amend it so that it will highlight all student & father names which appear more than once. (2nd and last entry in above example.)
