framesets

Can anyone help me, this might not be possible

i have two frames in a frameset

if i click on one frame i want to load information into the bottom frame.

Now when you click on the top frame, this makes a call to a class in the asp.

The function in the class does its magic, then i pass the html i want to load into the bottom frame into a function in this bottom frame.

I then want to load it onto the page using this function

Public Sub SetHTML(ByVal strHTML As String)
'Server.Transfer("mainPanel.aspx")
Page.Response.Write(strHTML)

End Sub

but all i get back are server errors :(

am i trying to do something impossible, or is it possible to load the information onto the page?

i dont want to use javascript if possible :(
