I wrote a simple function in visual basic that uses Sqrt(), NormDist(), and
Power() functions. I can use these functions in any worksheet, but when I
include them in the Visual Basic function, it says "Sub or Function Not
Defined" for each of the above functions. However, it did not complain for
the Log() function though.

Help from Microsoft says that I should find WPS.EXE file, compile it from
some other computer, and then ... - totally over my head since I have no clue
what it is asking me to do. Wondering if you would have any simple and
reliable solution?
