marmalade / jam

Jam is not the same as jelly but it all depends on where you're from. What the Americans call "jello" I call "jelly" but whenever I've made it I've used jelly crystals not juice.

Jell-o is the name of a brand that makes jelly. The proper UK word for jelly is gelatin, which is also sometimes used in the US. Jam and jelly/gelatin are two different things.

In the US, "Jell-o" is the brand name for what we'd call gelatin. "Jelly" is what we call a certain kind of fruit spread, similar to Jam but for the fact that is is devoid of fruit pieces.

Well that clears things up. I don't think that you can get what you'd call "jelly" in America in Australia. I don't know why you'd want it, sounds like the poor cousin of jam.
