1 - The GDPR course was last completed 15/11/2020 and should be renewed annually; so was overdue by 16/11/2021
As it is overdue I would like it to show in red.
Caroline,
I understand, that means there's just one missing step: You have to calculate the expiration date.
Let us assume you have 15/11/2021 in C2 and the condition in B2.
=EDATE(C2, IF(B2="Annually",12, IF(B2="Every 2 years",24,36)))+1
That calculates the expiration date, now use my solution from my first post.
Andreas.
