Hi all
I have a sheet that performs a series of calculations based on a
single value and culminating in another single value.  Also the series
of calculations is too complicated and long and numerous to do in a
single calculation.  What I have is, in another sheet, I have a range
of that single initial value, from -90% to +90% of the initial value,
and I'd like to somehow calculate that value resulting from all the
various initial values and insert them in the first sheet...how can i
do that?

for example:  sheet A contains the range of initial values and the
result of the calculations performed in sheet B

Percentage     Initial Value     Result
-90%              10
-80%              20
...                  ....
0%                100                  300
10%              110
20%              120
...                  ...
90%              190

sheet B: a series of calculations based on the initial value.  Ex:
initial value is set to 100 and results after a long series of
calculations is 300...

Now i'd like to assign something to the -90% row of the Result column
in sheet A such that it would (in the background?) insert 10 into the
initial value of sheet B, do the calculations, and return that final
value to that locations...any ideas?
