Hi,
I am trying to create some time series functions in excel. I want
these functions to take advantage of the columns and rows in excel.
For example, the most basic function is the difference function, which
is just the difference between one value and the one above it. So for
example, I want to have the function d(a4) which would be equal to the
excel formula "=a4-a3". Is there any way that I can write a vba
function that will tell me what location the formula is referencing.
For instance, say I put the formula "=d(a4)" into cell g1 and the value
in cell a4 is 12. Is there any way for me to figure out that the
location of the cell being referenced is a4 instead of/in addition to
learning that there is a 12 in the cell being pointed to?

Thanks,
Andrew
