How do you add contacts into groups?

[AC Question]

I know how but whenever I click add members/contacts, it said no results... I tried to type my friend's name and their phone number in the "friends" group and it doesn't work... I even tried to use the methid by tapping the menu, add group, and add member... Help me please!!! BTW this is Galaxy S3 and 4.3 (jellybean)

Welcome to Android Central! Can you clarify--are you in the Contacts app, and trying to add a contact to a Google Contacts group? Select a contact, tap Edit, then look for the Groups field. Tap the dropdown, and select one of your Google Contacts groups for that contact to belong to.
