The COUNT function should do what you want. https://exceljet.net/excel-functions/excel-count-function
If that's NOT what you're looking for, it would help if you posted a copy or a resemblance of your actual spreadsheet, along with a more complete description of what you are looking to do, and why COUNT isn't the solution.
I ask that because your request is a bit ambiguous. For example, you use and even capitalize the word "Constants" -- but SUMS often include variables as well, and COUNT would include them, but it might appear that you don't want variables to be counted. You see the potential for confusion.
