filtering

[mk sabeel]

hello sir,

i have a form which has a subform1 and the subform1 has
subform2

i am able to filter main form for a particular number of
feilds using the advanced filter design
but i am unable to filter the subform1 feildand subform2
feild such that when i apply the filter by
clicking "filter all" button i must get a records
corresponding to [mainform feilds + subform1 feilds +
subform2 feilds].
how do i achieve it

waiting for a stimulating response
thank you,
sabeel
