Well, you can transfer the added figures from one worksheet to another in two ways.
Here follow the steps to do so:
Copy the cell from the original sheet, then go to the new sheet, but do not paste. Do Edit>Paste Special>Values. This will copy the value instead of the formula to the new sheet.
In a second way:
Set up a formula on the new sheet that points to the total on the back sheet. If your total is on Sheet2, cell D20 you would enter this formula on sheet 1: =Sheet2!D20
And then, as you change data on Sheet 2 and the totals change, they will automatically update on Sheet 1.
Try anyone, that is easier for you.
