I want to enter"Yes" to the column Match if a Form has more than one row for the same State. For example, Form A has 2 rows for NY, so it is marked Yes. What is a good formula for this?
| State | Form | Match |
| NY | A | Yes |
| NY | A | Yes |
| CA | B | No |
| PA | C | Yes |
| PA | C | Yes |
| NJ | D | No |
