I’ll try not to think about what text this thing is spitting out–yikes!

Anyhow… I see no errors at all.

You can’t assign variables in the middle of a list, instead you would move this part to the output assignment so it would actually create the variable that could be evaluated by the ..., r = recipies.selectOne, r.name] instance:

[f=createInstance(ingredients.flour.selectOne), createInstance(b=ingredients.flour.selectOne)]

Like this:

Why does this happen?

Perchance recognizes and evaluates the f variable assignment block I’ve mentioned before as the child of the list pie which is a child of the list recipies, making it unusable when called it directly within the variable’s name. To fix this you’d need to execute that assignment before the recipies list is evaluated (as I’ve said before).
