Oracle Forms

Hi,
I'm using forms 6i
This thread is the contination of below thread, but since the topic is different i'm posting as a new thread
2174635

I have a multirecord block with columns pack group serial, pack serial,pareint id,pack type, weight etc...
The below said lov is attached to parentid
i have 2 columns in lov with values

PACK_GROUP_SERIAL           PACK_SERIAL
1                                        1
1                                        2
2                                        1
3                                         1

But I'm showing only pack_serial column in the lov
And based on the current record's pack group serial, i need to show the packSerials
like if my current record's packgroup serial say 1, the values in lov becomes 1 and2
for 2 and 3 packgroup serials values are 1
So i need to filter the values from the lov based on the packgroup serials
Is there a way?

Thanks
