BSP enhancement

Hi,

I have added 3 custom fields to BSP in selection.bsp, those are displaying in the brower too. and these 3 flds are for selection criteria.

But I want to add logic to selection.do.

1. The input parameter entered for newly added flds are not displaying..

For examle If i enter the value for newfld1..and selecting the option display selection.

the value is not staying in that fld(just like Hide fld)

2.

I want to filter the values based on the newflds.

Where I need to add the logic

Plz Help me...
