"Flag" Unique Values with Multiple Criteria

[sfleming]

I am trying to create a formula that will "flag" a single, unique combination of column A and column B.

Column A is a unique ID, column B is a code, column C is the expected output of the formula.

I only want to count the A3-A5 (2)/B3 and B5(2) Missing combination once. I only want a single instance flagged with a 1 (in column C). Also, I don't want the formula to be dependent on sorting by unique id, etc.

I did create a formula with SUMPRODUCT() that counted how many column B instances for each column A instance, but it didn't flag the unique values.

Please help! Thanks!

All the options that were shared work - thank you; however, I am still having a problem with Excel locking up when running these formulas. I have any where from 30,000 - 50,000 data rows. I finally killed Excel after it was not responding for 40+ minutes.

Anyone know of another formula or a VB algorithm that would do this caculation quickly (without locking up Excel)?

Thank you! This forum has been great. I appreciate all the help I am getting.

Like Mike's suggestion, but it uses faster IsNumber/Match instead of CountIf...
