Need assistance to configue products for LAR's track

I've hit a brick wall. I'm wanting to add more products to the LAR's " PL - Food" track and others like it. I'm adding the KUID of the product 20 Gal milk cans to the CONFIG of the LARS PL-Food like the others are from the products that are already there.
Once I submit it, go back into Surveyor and check, it's not there. Obviously , I'm not doing it right.
