SUM based on two conditions in an array with varying lengths

[jd354]

Hi, I am new to forum and just realzied I had posted my question in another post, so I am posting a new thread. Is there anyway to delete my posts that are in the other one?

Here is my issue (example attached). I am trying to sum multiple data based on multple conditions. In my example work book, I need the output to look at the month in cell N5 and then return the sum of all the data from the array that has the same code as in column K.

I have been able to get a function that gives me the first number that meets the criteria, but not the sum.

Your help or guidance would be great!
