finding the results of changing 4 variables

```Hi, I'm working on a 10 year financial forecasting model for an investment
fund.  The end result is to calculate the IRR.  There are 4 variable inputs I
would like to change, and observe how the IRR changes as those inputs change.
In other words, I would like to play with changing two different fees, the
fund size, and the expected return, and see how changing those impacts the
IRR.

Is there a way to do this on one sheet without manually changing all these
inputs?  I think Scenario or Data Tables might do it, but I'm not sure.

Thank you.
```

```irrhelp  -

For single-factor sensitivity analysis, where usually you keep three inputs
at base case and vary the fourth, you could use a one-way data table.

For two-factor sensitivity analysis, where usually you keep two inputs at
base case and vary the other two, you could use a two-way data table.

The data table approach is described in my free chapter, Sensitivity
Analysis Using Excel, available from the Chapters page at www.treeplan.com.

An alternative is to use an add-in to automate similar analyses. My SensIt

Finding a Median
I'm trying to write a query that will return a median for various values taken from a previous query. I've seen some suggestions in my searching, but I haven't been able to get them working. They are also all from before 2003 and refer to Access 97 and 2000. Has any functionality been added to 2003 for this? Or is there a non- code-based way to do it? I've seen it suggested to write a code to open the query, sort it, find the total number of records, divide it in half, then seek out the middle record using that value. I'm still very green when it comes to code, though...

Printing changes from 2000 to 2003
Documents that were set up in 2000 with printing set to say one page, are now printing to 2 pages or more in 2003 as if the printing set up has not been remembered. Does anyone know of a way to get around this without changing the print set up in every document that is opened? Thanks Shelagh Maybe being more conservative in the page setup would help. (I'd guess that this is more a difference in printers/printer drivers than an excel issue.) Use the settings for the worst printer you can find. Then hope that you found the worst one.

Upgrading reports from CRM 3.0 to 4.0
Having spent around 10 hours trying to upgrade a custom report from CRM 3.0 to CRM 4.0, I thought I’d post a message to share my pain and the solution!

I have been unable to find any documentation about this. If you have a custom report that is based on a standard CRM 3.0 report (i.e. it has the CRM_FullName parameter & UserInfo dataset) and upload it into CRM 4.0 then try to run it, you may get either of the following behaviours • Th...

How do I print 4 different postcards on one sheet in Publisher

The templet is the same everytime as far as the design of the card. What is different is the description on each and the picture. Currently we are having to print 4 of each card, each day. This works fine as long as there is not a change in the wording of the ad the next time it is ran or a price change. This is getting to be confusing, wasteful and causing mistakes.
