I tried to split the text in Course Release date to two column if there is more than two dates.
For Course release date original column, I used
=LEFT([Course Release Date]@row, FIND(" ", [Course Release Date]@row))
For Course release date if refreshed column, I used
=RIGHT([Course Release Date]@row, LEN([Course Release Date]@row) - FIND(" ", [Course Release Date]@row))
I am not sure why it is not working and left column showing blank and right column pulled the whole text?
