UDF's
 

I'm trying my hand in UDFs. In practice I created the following UDF in a
module

Function Area(Length As Double, Width As Double)
Area = Length * Width
End Function

Back in work book, I type =Area(A1,B1) in cell C1.

The result shown in the cell is 0. The result shown from the formula
dialogue box is 24. I have no idea what's going on. Any help is sppreciated.

UDF's
 

try (Length As Range, Width As Range)

I used your exact code in a standard code module and it worked like a charm.
So just to verify...

Your code is exactly as posted. No spelling mistakes or such. Do you use
Option Explicit at the top of your code module?

What do you have in A1 and B1?

Perhaps the numbers are actually Text?

Format to General then re-enter the numbers in A1 and B1

Interestingly enough I tried that and text or number makes no difference. It
works in either case. I assume that it is becuse he declared the arguments as
double causing XL to do an implicit conversion. If I enter text such as abcd
the function returns #Value instead of 0.
