Type in Type

What I'm trying to do is something like this:

Public Type A1
    SubItem1 As String
    SubItem2 As String
    SubItem3 As String
End Type

Public Type A2
    Item1 As A1
End Type

Obviously it doesn't work (Forward reference to user-defined type error). Is there a way of doing it (use an user-defined type in another user-defined type?)
Thanks for ANY help

I got your code to work in VB6 Enterprise. What version are you using?

I have VB 6 ent also and I finally figured out how to use this code. What I had in my program was:

Public Type A2
    Item1 As A1
End Type

Public Type A1
    SubItem1 As String
    SubItem2 As String
    SubItem3 As String
End Type

...and it causes "Forward Reference error". I can't believe that all I had to do is to switch places of the A1 and A2. It reminds me of old TurboPascal days where you were not able to use a function A from function B if the fA was declared later than fB.
Thanks for telling me it worked. After that I've figured it out.
