Excel - Conditional Forumla Question

Expert: Richard Rost - 7/8/2009

Question
Good Day

Thank you for taking the time to answer my question

What I am trying to do is to know 90 days before a day is to come in to effect and to have it high light red.

spread sheet. I was given this formula
=AND(INT(NOW())>0,INT(NOW()-B1)<=90)

I was given this formula by another expert but it doesn't seem to be working.

also how would I go about setting up a formula to know how many days past due something is?

thank you in advanced

Andrew

Answer
Just make another field and set that field equal to:

=IF((A1-90)<=TODAY(),1,0)

Where A1 is your date. Format this cell as a number. Now, use conditional formatting to set this cell's color if it's 1 or 0 (true or false).

Excel has a feature called Conditional Formatting that you can use to change the format (color, font, bold, etc.) based on the value of the cell.

See this FREE video tutorial on my web site for instructions on how to use Conditional Formatting.
