I am trying to perform a For Each Loop on a nested array and VB is yelling at me

The nested array structure is this.

MainArray(0)
    SubArray(0) = "Some String"
    SubArray(1) = "Some String"
    SubArray(2) = "Some String"
MainArray(1)
    SubArray(0) = "Some String"
    SubArray(1) = "Some String"
    SubArray(2) = "Some String"

...and so on.

Where SubArray always contains 3 total elements and MainArray can have any number of elements which are SubArray.

Here is what I have.

(Toggle Plain Text)

Private Sub ProcessArray(byref MainArray as Variant)

    For Each SubArray In MainArrary
        DoSomething SubArray(0), SubArray(1), SubArray(2)
    Next

End Sub

Upon attempting to compile I get this error.

For Each control variable must be Variant or Object

I've tried to declare SubArray before the loop like this.

(Toggle Plain Text)

Dim SubArray(2) as Variant

and even like this.

(Toggle Plain Text)

Dim SubArray() as Variant

But I can't get anything to work

Can this just not be done in VB?

Thanks in advance to anyone who posts.
