I have figures in certain cells (A1 = 5000, B1 = 3500 etc) as example

In Column C running down (C1, C2, C3 and so on) I input in each cell 150 and it reduces A1 (5000) each time (5000 - 150 = 4850 and so on till A1 = '0'.

Can you please help me so that once Column C has been entered with the 150's and A1 then = 0 or shows a minus, if I add another 150 to Column C, it will start to reduce B1 (3500) figure or when there is a minus in A1 etc, it will reduce B1 total.

I hope this made sense

Many thanks
