Return Count of Instances of Strings in a Column Matching List of Strings in Another Column

I'm looking for a formula that can be applied to a column that will return the count of instances of strings defined in another column. Refer to the attached example:


Ex. 1 should return 6 because there is 2 instances of item1, 2 instances of item2, and 2 instances of item9. Item3 and item4 are not included in the count because they are not in the Criteria column.

Any questions let me know!

This worked for me, though there's probably a better way.
