Compilation error after go gnerate

[maxtar]

I've changed phones_format files and run go generate command. No error was shown. But when I trying compile my application I getting the follow error:

 go build
# github.com/icrowley/fake
..\..\..\..\icrowley\fake\fake.go:96:20: undefined: data

I compare old data.go and after generate. data variable not exist in it.
