Dynamic parameter for begin and end date

hi, have stored procedure returns 3 items, id, begindate , enddate.  on report have 3 parameter 1 id, , 2 dates.  want select id , in data begin , end date id date parameters.

it working when form loads becouse of default value of id parameter but when select different id not change value of data parameters.

any idea why?

thank again.

 select id, begindate,  enddate

 where id = (@id)

 and begindate = (@begindate)

 and enddate = (@enddate)

 

 if have multi selection use in

 

  select id, begindate,  enddate

 where id in (@id)

 and begindate in (@begindate)

 and enddate in (@enddate)
