Hi

P.e.
A1="Value"
B1="CumSum"
B2=IF(A2="","",SUM(A$1:A1))
, and copy B2 down for as much rows as you need.

I don't know if this is the right group ... or if i should have put this
in
the programming group ... but here is my question / problem ...

I have been using the TI 89 and there is a function called cumsum - it is
for cummalative sum of a colum to another colum. this is a valuable
function
for me ... and my dept is moving to "bigger toys" ... one of them is Excel
... i would like to know how to create this function in Excel. Example
....
in colum A, i have twenty numbers ... in colum B, it would give me the
accumative total of each line from colum A. Is there a download that would
place this funtion or a program editor that i have to use to place it in
the
Excel program ... if the latter is the case ... how would i write the
function / command and install it for permanent use?

Any help on this will be greatly appreciated.
