مشکل در ساخت ستون جدول name با SQLite

استاد سلام،

من الان در جلسه 25، زمان insertContact با خطایی مواجه میشم که میگه اصلاً نمیتونه ستون name رو درست کنه در جدول

ممنون میشم منو راهنمایی بفرمایید چطور برطرفش کنم؟

خطا:

E/SQLiteDatabase: Error inserting number=81223344553 name=Amir8
    android.database.sqlite.SQLiteException: table myContacts has no column named name (code 1 SQLITE_ERROR[1]): , while compiling: INSERT INTO myContacts(number,name) VALUES (?,?)

}

حداقل به نظر خودم دقیقاً مثل فیلم کد زدم (احتمالاً یه جایی خطاست اما متوجه نشدم بعد 1-2 ساعت گشتن)

پیشاپیش از لطف و پاسخگویی شما متشکرم
