I am managing a do-not-call list with a large contact
database. How do I establish a poitive/negative match
from source data.
eg. Cell D7 value is: 212-555-1212.
The source worksheet has a list of all phone numbers in
Column A.
So, if the value of Cell D7 matches a value in source
worksheet Column A, I can conditionally format it.
Thanks in advance.
