Create Countif Macro to count blank cells if arguments from multiple sheets add up and post findings on a final sheet

[glockgal42]

So I have three sheets "Yard", "Available spaces", and "Yard configurations"

If cells in Column K of "Yard configurations" equals Yes, and Cells in column B in "Yard configurations" equals ParkingLocation then use text in Column C of "Yard configurations" to find the same text in column A of "Yard" and count the blanks in column B of "Yard"

Then once the data is collected, put the number in a specific cell on "Available spaces"

Can anyone help lead me in the correct direction?
