Count Conditional Distinct Values

Hi all,

I am using the following array formula to count distinct values in column A where the first two characters is "12" and corresponding cell in another column E is not blank:

PHP Code: 

=SUM(IF((LEFT($A$2:$A$67,2)="12")*($E$2:$E$67<>""),1/COUNTIF($A$2:$A$67,$A$2:$A$67))) 


But it is not giving the correct result - see attachment. It should be 63 instead of 62, but I can't figure out why.

Any help, please?

Thank you,
