how to calculate the ressult from input 1 and 2

[vho]

Thank you for your time and please help me on this program. I looked into the function and this problem can not be solved.

So, help me solve this problem please.

I'm very new to VBA. It would be very kind of you to write the program out so i can learn from this example.

i have the input 1, 2
result (C3) = B2 + A3 - B3
result (C7) = B3 + A4 - B7
result (C12) = B7 + A8 - B12
result (C13) = B12 + A13 - B13
result (C14) = B13 - B14

input1	input2	result
	20
200	50	170
200
	30	220
250
	5	275
100	80	25
	20	60
