I need formula to calculate a date to start checking on a column example
Installation date, need to add 2 weeks prior to start follow up to upcoming information (This will be on the left of the Installation date column)
If I'm understanding your question correctly-- are you saying you need a formula that calculates 2 weeks before the install date?
Should populate your install date - 14 days
I agree with @Spark@Spark's solution. Were you able to get it working?
