compare with another form and delete the row if criteria Matched

Hi,

I have two form FormA and FormB , There are two  common fields between two forms. Below is the screenshot of the two Forms,

FormA:





Note:

TV station : Look up field of station Name of Station Form

Network -01 ; look up field of Network name of Network Form
Network -02 ; look up field of  Network name of  Network Form
Network -03 ; look up field of  Network name of  Network Form
Network -04 ; look up field of  Network name of  Network Form


FormB:





Note:

TV station : Look up field of  station Name of  Station Form

Network  : look up field of  Network name of  Network Form


what I am trying to do is that --

 In the FormA when I update any network name like   Network-01: ABC  to something else like Bounce TV then A script will delete the row of corresponding TV station and Network in the FormB.

For instance here it should delete the first row  of the FormB .  Since it is matched with the T V station name and Network Name of the FormA.

So After deletion the row then  the FormB looks like below




can anyone please help me.
