Hello all. I am new to numbers and this is my need. I have taken a blank spread sheet and on the left side column C I have listed my bills by weeks, on the right side column H my income. I am able to get the sum total of each column at the bottom on line 39. I also want to get the amount left over. I need a formula that will subract C fom H and put it in column G on line 39. Does anyone have any ideas ?
