Iterations of complex calculations
If it is as easy as you suspect, likely there is a solution out there. Spend
some time with Google. Maybe you'll stumble upon something.
Else, maybe reconsider how easy it is...

That's a shame.
One of the most elementary things that a computer should do is "work the
sausage factory". It's where computing started!
"Here is the way the factory works, here are a few ingredients (in varying
proportions), what is the result for each combination?"
It seems that one needs to be a brain surgeon to program in VisualBasic to
do something that I knew how to do using BBC Basic (all those years ago!).
Thanks for your help - likewise to driber2 - but the only realistic (and
time-effective) manner to do this is to punch the parameters into the model,
copy the result and paste-value it into the correct cell of the summary.
Note to Microsoft or anybody else who can write Excel 2000+ Add-Ins: invent
a function =CALLSCENARIO(<name,p1,p2,p3,...pn,o):
* where <name is a defined scenario on the server worksheet (that might
exist in a different worksheet than the client worksheet), e.g.
(c:\test.xls[Sheet1]!"Scenario Test");
* where p1...pn are the parameters that the scenario requires; and
* where o describes the outcome cell required per scenario, e.g. if the
scenario summarises 3 cells, then o = 2 would return the second cell.
In cell, say, B10, the user punches in =CALLSCENARIO(Test,a10,b3,100,200,3).
How easy is this?!
Many thanks.

I don't believe the Scenario Manager can be used in that manner. Perhaps
there is a VBA-based solution to your problem but you said in your original
post that you're not interested in going down that road....

Thanks Dave.
This is more like it, but it is incredibly tedious. Rather than type
parameters into dialogue box for every combination of parameter required, can
I use a formula to run the scenario, taking its parameters from elsewhere in
the calling sheet?

I would look at the Scenario tool.
Tools--Scenarios...
Post back if you have questions.

In Excel 2000, I have a complex calculation (in a worksheet) that takes 4
parameters and uses them in 4 different sub-calculations, involving
relative/conditional sub-sub-calculations. In effect, it's a model.
Having done this, I now want to pour a series of numbers into this model, to
see its effect on various combinations of parameters.
Rather than type each parameter in, copy-paste-value the result into a
summary table, how can I get Excel to run the model on call from a worksheet?
I am illiterate in VisualBasic, so anything that avoids macroes would be cool.
