I made this twice recently and it only separated into two layers....what did I do wrong?

I found a box of Cherry 1 2 3 Jello-O in my cabinet a couple of weeks ago!

I remember this too. At one time Jello offered (plastic) gray parfait cups. I think my mom still has them.

Oh, I forgot to mention, there is a new version of this product on the shelves (at least in Canada) made by Dr. Okter (weird name, I know, but the product is identical)

Yes Jello 1-2-3. I would have 3 distinct layers and it was pretty darn good. I can only remember orange, but I know there were other flavors.

Wow my mom had those parfait cups and they were gray. She still complains that they stopped making the Jell-O 1-2-3. I remember it as being pretty darn good.

Dr. Oetker makes the Jello 1 2 3 version and comes in grape, strawberry, lime and orange http://www.oetker.us/en/product/dessert-mixes/gelatin
