each assay volume for month

Good morning everyone,

I'm reaching out to seek assistance with calculating assay volumes. I have data on assay volumes for different types of assays offered by various clinics. My goal is to calculate the each assay volume for each clinic from January to December. I've included a tab labeled "final calculations" where I'd like the final data to be formatted.

I've been trying to figure this out on my own but haven't been successful. Your help would be greatly appreciated as I'm eager to learn. Thank you in advance for your assistance.


Thanking you,
Stan
