where is your param variable defined? For that matter, where are you declaring the con, cmd, da, and ds objects?
I was able to duplicate the problem you are seeing. I believe it is related to the fact that your DataSet object doesn't go out of scope when the button_click event ends. SqlParameters and DataSets are a little wierd. They don't like being reused. Once you add the paramter as "Joe Customer" the first time, it...

Should I dispose of each child control before disposing of the parent control?
I am using Visual Basic .Net 2005 professional.
