Counting values in cells and a range

Hello!

Here is my problem:

I have a column, we'll say E18:E2500. In the cells in that column are four digit numbers. Some of these cells may have multiple four digit numbers separated by a comma and a space. (example: 2020, 2100, 3120) Some other cells in the column may also share the four digit numbers (I mean duplicates).

So I'm trying to write a formula to sum and count all the unique values in the cells and in the range.

This is what i've been trying to use but it counts all the values with no regard to duplicate values:

=SUM(IF(LEN(TRIM($E$18:$E$2500))=0,0,LEN(TRIM($E$18:$E$2500))-LEN(SUBSTITUTE($E$18:$E$2500," ",""))+1))

Can anyone help??

Take out the 2nd condition:

=SUMPRODUCT(--ISNUMBER(MATCH("*"&ROW(INDIRECT("1000:9999"))&"*",E18:E2500&"",0)))
