Default value in textboxes are lost when a drop down does a post b

We have a couple of dropdown boxes and a text field as parameters to a report.
The options in the second dropdown box depends on the selection of the first
one, so I'm happy with the fact that a post back occurs when the selected
option in dropdown box 1 is changed.
However the value entered by the user in the text box get overriden by the
default value, that I'm not too happy with.
Is there a way of preserving user input?

FredFred, have you tried NOT setting a default for the second parameter?
If that doesn't work then I think the answer is no!
