Question of table

[38348259]

Dear All, I have a question about the group address of table. There are some lines in a GA table, e.g. 

table = {
{onoff=1/1/1, feedback=1/2/1},
{onoff=1/1/2, feedback=1/2/2},
{onoff=1/1/3, feedback=1/2/3},
{onoff=1/1/4, feedback=1/2/4},
}

I want to define a local var which called "num",which means when I trigger "1/1/3", the "num"=3, when I trigger "1/1/1", the "num"=1. How can I write the script?

Thanks a lot
