In NewStockbtn_Click()...

I changed:

    Dim myPrompt(7), infoArray(7), returnInput As String

To:

    Dim myPrompt(7) As String, infoArray(7) As String, returnInput As String

and it was happy.

Never do that.  You might think that that designates all three variables as String, but you'd be wrong.
Only returnInput gets treated as a String here; the others are treated as Variant.  Do like Idle_Mind
does and explicitly declare a type for each variable (even if you want that type to be Variant).

Yes I realize my error now. Thanks
