>Thanks Henry,
>the VHeaderKey is the parameter variable name, and when I browse the view from the IDE I provide it by Pasing the value of the expecetd key from the original table. (which works fine only the first time or if I am not modifying any fields on the browse).

I agree with Henry, especially in light of the above. I understand VHeaderKey is the paramater, the question is: what is the state of the source of the parameter? The visibility of that parameter source is the key... do you have the code which is used prior to your sample in which the value is placed for the VHeaderKey?
