In Formula Is, you need a formula that evaluates to either TRUE or FALSE
So you would use =$C$70$N$70
Then click the Format button on the Conditional Formatting dialog and select
font colour red
Have a look at Deborah's site:

Hi everyone,

And again I need your help. I have to admit I am not so familiar with
conditional formatting and probably I misunderstood the concept.

In cell C69 I choose 'Condition Formating' and choose 'FORMULA IS' and
wrote
this formula
=IF($C$70$N$70,) 'CONDITIOAL FORMATING TO TEXT COLOUR RED'
but notthing happened. What did I do wrong?

Thank You
Albert
