Adding same cell

How can I add the same cell to itself?? and then have the value given in another cell??

EXAMPLE

A1 to be used over and over to create a running total.

so...A1=A1+A1 and for it to keep the value.
so, it would be like 20+20+20 = 60 and the value 60 stored in another cell
perhaps A2

I can write a program to do this, but it would be DOS based, and I don't have the time...so any help would be greatly appreciated.

I know I can creat continuous cells to do this, but I don't want to do that, because I would have a page full of enteris, when I believe it should be possible to creat a running total with just one cell.

Thank you for any help you can offer!

 

I don't really follow. This code in the worksheet module

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address <> "$A$1" Then Exit Sub
Range("B1") = Range("B1") + Range("A1")
End Sub

gives you a running total in B1 of values successively entered in A1.

If this doesn't fit the bill, post back.

Thank you for your advice, however, it is solved now. My son who is 17 years old, was able to give me a method to achive what I am trying to do.

Thank you again, for you help.

Excellent! How?

well, he did
b4+b5 in the b4 cell
Then went to tool/options/calculations then checked ITERATIONS then increased the maximum change to its highest, and it worked..

Of course, it can work for any cell number, the above is just what he used to demonstrate his method.

 

>> tool/options/calculations then checked ITERATIONS

I see. Same result as the code but achieved "in-cell" by disabling circular referencing. Impressive.
