dictionary object holding multiple dictionaries?

[lemkepf]

Hello all! I'm wondering if this is possible? Basically i need to create a 3 dimensinal array, but i have to be able to refernce the variables by name, not number.
I think i have been able to declare a dictionary object inside of another, i'm wondering how i would get the values back? kinda like this:

dim maindic
Set maindic =Server.CreateObject("Scripting.Dictionary")
dim subdic
set subdic= Server.CreateObject("Scripting.Dictionary")
subdic.Add "Price", "$40"
maindic.Add "sub", subdic
Response.Write("The value of key main - sub is: " & maindic.Item("sub".item))

That code doesn't work, stuck on the response.write line. Any idea how i can do this? Thanks for all the help!
