Count occurences and return total

HELP! I know someone here can help me! I want to count the number of times
a specific ID number occurs in a column, and return the total count in the
cell adjacent to each occurrence of that number:

ID # Combined Count
343 1
654 3
654 3
654 3
109 2
109 2
433 1

If anyone can advise, I would greatly appreciate it! THANKS!@

NEVER MIND! I figured it out myself (after MUCH trial and error). Here it is:

=COUNTIF(A:A,A2)

Thanks anyway!

Try one of these:

With ID #'s starting in cell A2, enter this formula in cell B2 and copy down
as needed:

=COUNTIF(A:A,A2)

If the ID #'s are grouped together as in your sample then this is a little
bit better. A1 and B1 are column headers.

Entered in B2 and copied down as needed:

=IF(A2=A1,B1,COUNTIF(A:A,A2))

Using this formula saves from doing a count on every entry and just does a
count on each distinct entry.
