Taking default value while passing a parameter thro a prompt

[VVVD]

hi folks

In reportnet
I have a list report with 3 columns and the last column total is a caluculted column on which I have to do drill through.
I have a 6 prompts for this list report data.

I think I need to have these query items(from the prompts) int he list bcos I want to filter the data on these query items.So I included these in the list report data items.

Even I dont select one of the prompt its taking default value while drill through.

I have checked all the following from properties


Default selection
Filter of that prompt
Data expression
Static values

but no traces of default value. any suggestions?


Thanks for ur time
