Frankly your constraints has me baffled.

Solver is set to minimize C12 by changing C17:G17 where you have a max constraint i.e. equal to or less than C4:G4 but C17:G17 has a min constraint i.e. 0

So in order to minimize H12 Range C17:F17 will be 0 and G17 as it contains a formula will be equal to the value in R1?
