I need to return a list in a third column of only the values from Col 1 that are fully filled out in Col 2.
In this case it would list A and C. In other words if all values A in Col 1 have corresponding values in Col 2, display value A once in Col 3 to show that its filled out and ready for further processing. B shouldn't be displayed in Col 3 because some B cells in Col 1 still have empty corresponding cells in Col 2.
| Col 1 | Col 2 | Col 3 |
|---|---|---|
| A | 1 | A |
| A | 2 | C |
| A | 3 | |
| B | 4 | |
| B | ||
| C | 5 | |
| C | 6 | |
| C | 7 | |
| C | 8 |
This is part of a compliance tracking document that is updated as info comes in, and once a subset of Col 1 is fully filled out in Col 2, I need to be able to tell at a glance that everyone has provided the necessary info which means I can now take the next step in the compliance process.
