That's correct - just pass a list or tuple. However, that is rarely the complete answer - what *type* of variant should be in the array? Since you only received this error when you changed to Missing, it appears LabView *is* seeing the real param as an array of variants, as it does not return this specific error. Sadly there is no easy way to explicitly specify the exact variant type, other than using InvokeTypes.
