I am trying to write a UDF but I am unsure how to request multiple
arguments of the same type? I am looking for something similar to how
the Sum or the average looks. You can select multiple ranges or cells
and it just gives you another number. Number1, Number2,
Number3...Number30. How is this accomplished?

Thanks,

Look at the Optional and ParamArray keywords.
