| Hello-
|
| I have a bunch of data in excel right now, and I need help writing a formula
| that will automatically do subtractions.
|
| Here is an example to help explain what I mean...
|
| In column A I have 400.00. In column B I have 60.00, which means I want
| column C to be 340.00. Now, Column A is constant at 400.00, but the data in
| column B changes with each row. So I was wondering, is there a formula I can
| write in the C column that will automatically change to whatever row I am in.
|
| Example: the formula in row 1 is =a1-b1
|
| Now if I were to copy and paste into the next say, 20 rows I want the
| formula to automatically change to =a1-b2, =a1-b3, =a1-b4, ect.....
|
| Does this make sense to anyone? If not, I would appreciate it if someone
| could help me out, I could even send the excel doc. to your email. Any
| information would be greatly appreciated! Thank you!!
