Hello, I'm have a dataset with 3 columns of dates. What I would like to do is create one single column which prioritizes putting Date 1 in it, but if Date 1 is missing it places Date 2 into the new column and finally if both Date 1 and Date 2 are missing it places Date 3 into the new column.   Date 1 Date 2 Date 3 6/15/2017 6/14/2017       6/12/2017   6/15/2017   6/14/2017 6/15/2017 6/20/2017   Output should look like this Date 6/15/2017 6/12/2017 6/15/2017 6/14/2017   Thank you! ...
