Help: Multiple criteria involving strings

But the formula doesnt work when i put it in my original databse
shows #value errror,
I changed the column references to appropriate columns.
What do you mean by avoid pressing control shift Enter? That is an illogical explanation. MMULT is array multiplication function.
Anyway it is wrong, because it give 0 output when that is not the latest entry.
