What is going wrong here...
 

I have a matrix like this...

12 4 22
2 1 33
54 2 9

....and the following function...

Function myfunc(m)

myfunc = 2 * c

End Function

Passing on the matrix to exactly this funciton (letter by letter) in
Excel 2003 SP2 results in #VALUE!

Why? What is wrong here? My guess is that some data type definitions
are missing. Can somebody help?
