The errors are:
Lets say I enter Number 3 to edit a contact line 99 comes up with an error "Thread 1: EXE_BAD_ACCESS (code=1,address=0x60)". I do not even know what that means.

Delete Contact also is giving me errors. I am can't seem to see the error. The while loop on 99, 114, 130. I get the following error when I try to delete a name:
