I believe that you *are* missing COMPLETELY the initial instructions of
Cyber.
<<<"One Option, there are others- In Format>Conditional Formatting:">>>
Which means ... you are to use "Conditional Formatting"!
Which means ... you *don't* put the formula in the cells of Column I!
Is that perhaps what you did?
Anyway, with a quiet Sunday, and the lawn already mowed, would you like *3*
formats for Column I?
One for 7 days before due date,
One for due date,
And one for Past Due.
Start off by selecting I2 to I90.
While the cells are *still* selected, and with the focus of the selection in
I2 (colored white), click:
<Format> <ConditionalFormat>
Change "Cell value is" TO "Formula Is",
And enter this formula:
=AND(I2>0,I2>TODAY()-7,I2<TODAY())
Then click on "Format", and choose your font and pattern colors.
Then <OK>.
Click <ADD>, which allows you to set a second condition and format.
Click "Formula Is", and enter this formula:
=AND(I2>0,I2=TODAY())
Then click on "Format", and choose your font and pattern colors.
Then <OK>.
Click <ADD> again for your final condition and format.
Click "Formula Is", and enter this formula:
=AND(I2>0,I2>TODAY())
Then click on "Format", and choose your last font and pattern colors.
Then <OK> <OK>.
