    How to create a formula that keep tracks of new value.

    A B C
    1 10 0 =B4
    2 10 10
    3 10 20
    4 10 30
    5 inputting new values -- > C1 changes it's value from =B4 to B5 as new value gets created.

    How do I create an excel formula that changes itself (C1) to =B4 -- > B5 -- > B6 etc, whenever a new cell is created at B5 and 6 and so on.

    Re: How to create a formula that adds or subtracts, whenever a new cell value is created.

    Almost worked but this is strange, It gave me value on cell F15 however, the cells are filled until F18.

    I used this: =INDEX(F:F , COUNT(F:F))



    EDITED: I just used =COUNT(F:F) it gave me result as there are 15 rows same F15, despite till F18 cells are completely full.

    it fails to recognize values over F15 for some reason.

    Suggest you post a sample workbook so we can see what you see.

    [FIXED] I had to define First data in the range, simply F:F won't work F5:F will work where F5 is the head of the data.

    Re: How to create a formula that keep tracks of new value.

    If you want the last (bottom-most) numeric value in the column:

    =LOOKUP(1E100,F:F)

    Re: How to create a formula that keep tracks of new value.

    this may also work, but what is 1E100 in this formula?

    can I also use multiplication in my lookup formula? =LOOKUP(1E100,F:F) * B10 ?

    1E100 is scientific notation (a shorthand method for expressing very long numbers) for the very large number 1 followed by 100 zeros.

    How it works...

    If the lookup value 1E100 is larger than any number in the range the formula will return the last (bottom-most) number in the range. There is a 100% chance that no numbers you're working with are anywhere close to being 1E100.

    Yes

    I don't know anything about Google docs.

    It works in Excel.

    Re: How to create a formula that keep tracks of new value.

    it doesn't even work on excel.

    I used this =LOOKUP(1E+100,D:D )

    and the data is in row D. Nevermind I got my job done with the other formula, thanks for help.

    Sure it does.

    and the data is in row D.
    Do you mean column D?

    Here's a sample file.

    The formula will return the last (bottom-most) numeric value from column D.

    Start deleting the cells from the bottom of column D and notice the formula results.

    further more it also works on google docs now.

    Reason, your mistake :P its =Lookup(1E+100, D:D) instead you wrote =lookup(1E100, D:D)

    Excel automatically adds the plus sign.
