Hello everyone, hopefully someone can assist me in creating a column validation formula.
I have a column "EXPRESS / REGISTERED" and another "TRACKING NUMBER"
The "EXPRESS / REGISTERED" column has three drop down values "NO" or "EXPRESS" or "REGISTERED"
I would like to have a column validation formula in "TRACKING NUMBER" that forces the user to input data in "TRACKING NUMBER" when the "EXPRESS / REGISTERED" column value is either "EXPRESS" or "REGISTERED". The "TRACKING NUMBER" column can be blank when the value of "EXPRESS / REGISTERED" is "NO"
Hopefully I have explained this clearly and there is a formula that would work.
Thank you for your time and assistance it is appreciated.
