Cuando ! surely not!!

In the Community Centre module 7, one of the questions in the vocab test was: What is the Spanish for "how many". The answer was given in module 8 as "cuando". This is surely incorrect as "cuando" means "when" I think this should be "cuanto" shouldn't it?? Ian

cuanto/cuanta "how much" and cuantos/cuantas "how many". Haven't seen this module 7 yet but I'll be aware of this, yeah as far as I know cuando can never mean "how many" . I hope someone can answer for this.
