The value "123" is invalid



Novice here. Working through the Core Data chapter.

When running the program, and trying to enter a price, I get the following error no matter the value keyed in:

[quote]The value “123” is invalid.
Please provide a valid value.


After a few hours, I downloaded the code from Big Nerd Ranch. It has the same error.

Everything else works great.

Xcode: 4.6.3
OS X: 10.8.4

Any ideas are appreciated.


Of course, after hitting Submit I had an idea.

You MUST leave (or supply) the $ in the price field. With that, any number is accepted – with or with decimal point.
