I have two sets of data in columns A & B and also in columns C & D. Some of the content in column C & D does not appear in columns A & B:
A = reference numbers
00001, 00002, 00003, 00004
B = phone numbers for column a people
123456789, 234567890, 345678901, 456789012
C = reference numbers
(these contain SOME of the reference numbers that appear in column A)
00001, 00002, 00004
(NOTE: 00003 is missing)
D = phone numbers for column C people
(these contain SOME of the phone numbers that appear in column B)
123456789, 234567890, 456789012
(NOTE: the phone number 345678901 is missing)
How would I create a separate column that contains the phone number from column B of anyone whose reference numbers appear anywhere in BOTH columns A and C?
