Here's what I'm trying to do:

We are calculating a column of numbers

Line 1 $249,000 Sales Price

Line 2 $7,470.00 Adjusted Commission Basis
Line 3 $373.50 Additional Fees
Line 4 $7,096.50 Adjusted Commission Basis (Line 1 minus line 2)
Line 5 $5,322.38 Gross Commission (75% of the Number above)

Then I want to take the amount that is calculated in line 4 and add that to the Year to Date total which is in another cell.

Line 6 YTD Income: $173,101.22
Line 7 YTD Volume: $7,515,500.00
Line 8 Com Basis: $238,584.24

HERE'S WHERE I NEED HELP:

I need Line 6 to increase by the amount calculated in line 5. Since it is a year to date total, it is going to change each time. What formula will make it do this automatically?

I need line 7 to increase by the calculated amount entered into Line 1.

I need line 8 to increase by the amount entered into line 2.

This is probably really easy, I just don't know what to call it to search how to do this.

I appreciate any help! Thanks!
