I have an excel add-in file that was built by my teacher to perform
complicated gas and oil calculations. In Office 2003, I would search the C
drive for "funcres" and it finds an excel file called funcres.xla. I paste
my formula file into that same folder and then go into excel. I go to
Add-Ins and it appears as one of the functions you can add in by clicking on
the check box. I can then use my formulas just as I would use any other
function.

Now I have Office 2007 and can't find the funcres file anywhere on my hard
drive. Any ideas? Maybe the file is called something else?
