It seems like both your phone pattern and email patterns are improperly grouped. The "[..]" indicate that the contents can occur in any order, therefore it doesn't specify. For example: A phone number is XXX-XXX-XXXX where the x's are digits. Therefore the pattern should be something like this:


*I can't remember how the parenthesis works for the named grouping

The email should be something like this seperate the characters the come before the "@" symbol, and the characters that come after it like this:


*This isn't exact, but it should help you fix what you have.

sadly the answer still isn't that clear to me, can you be more specific?

You need to remove the brackets surrounding your answer because it's just saying the pattern needs to contain those characters but, it doesn't specify the order the characters are supposed to be in. Compare your answer with the one's I've specified and try to see what's different. Once, you understand that you should be able to tackle this
