Call VBA function that returns custom type from spreadsheet

Question

I have a vba function that returns a custom data type, defined as:

Public Type stockValue
        stock As String
        value As Double
End Type

Answer 1

You can only return data types that Excel understands from a user-defined function. Excel does not understand custom data types.

Instead you would have to return a variant array containing the 2 values from your custom data type. Then either you would array enter the function into 2 cells, or use another function such as INDEX to retrieve the value you wanted from the returned array.
