VBA Excel Function

[Josh]

I created a new function and saved the file as a .xla file
and imported it into excel. How do I make the help
information and the information in the text box? For
example in sum, when the Number1 box is selected, the
space below reads:

Adds all the numbers in a range of cells.

Number1:number1, number2, ... are 1 to 30 numbers to
sum. Logical values and text are ignored in cells,
included if typed as arguments.

This is the first time I have used VBA, but I figure thigs
out pretty well.

I never use it but Gord Dibben posted this:
It looks like a useful Add-in
