Hi
I am working on a user defined function in Excel, and am wondering if it is
possible to select what arguments to use in a function when the file is
opened.
I am thinking something like:

if c1= "Yes" then argument a is to be used - here_: "Yes"
if c2= "Yes" then argument b is to be used - here_: "No"
if c3= "Yes" then argument c is to be used - here_: "Yes"
if c4= "Yes" then argument d is to be used - here_: "Yes"

Function (a as string, c as string, d as string)
.....
