okay.. I have this website like this:
on the left column I have a dtml tree, and on the right side, I have a
content that using SQL method and requires a parameter.
but when I try to expand or collapse a tree node... it returns an error
because the SQL method on the right columns ask for a parameter.  I can't
assign a default value for the parameter, since it wont show the right page.
Is there anyway to add a parameter to the link on the expand-collapse part
so my right column won't return error.

I can't use a frame cause it's my web's spec...^_^

thanks guys..
