i populated the value in drop down.
Its working fine but the problem is how to fill the default value in drop down. because i want to bind the default value which im getting specify value from the table.because each row
im getting different values, like first row
CAR
, that CAR want to fill as a default value in drop down  and second row  as
BIKE
that BIKE  want to fill as default value in drop down  ( example drop down contain   car , bike , cycle).
In adobe form i binded like this
