Expression.Error: 2 arguments were passed to a function which expects 3.

[Anonymous]

I've written a function that is intended to intake 2 arguments (dates) and report the number of weekdays elapsed. However, when I invoke the function, it tells me that my function is expecting 3 arguments. Why does Power Query tell me that the function expects 3 arguments?

If I input a bogus 3rd argument, it tells me that the function is only looking for 2 arguments

Not my intention at all, just seemed worth investigating for starters.  Sometimes all it takes is another pair of eyes to look at something. 

All the best.

Well, now I feel silly. That was the issue, thanks!

Have you proved that the error does not come from the logic inside the function?
