What does this error mean i have never gotten it before?

here are my errors

GiftBag.java:22: error: cannot find symbol

double getLimit = in.nextDouble();

^

symbol: variable in

location: class GiftBag

GiftBag.java:34: error: cannot find symbol

double weight = in.nextDouble();

^

symbol: variable in

location: class GiftBag

normally when i write the code like that it works just fine but not this time for some reason, here is the rest of my code if you need it.
