There are multiple issuies:
1.when you pass group as argument when you call add_contact on line 22 none of group, first_name, last_name, title, mobile is defined. One way to deal with this is collect this information before you call the function, then pass it as argument. Another way is to remove the parameters of add_contact() and collect the information inside the function. However here comes next issue:
2 You collect that information in the body of add_contact(), but at the end, not before you try to use this information
3. all_contacts() and edit_contact() are not defined.
