Ошибка частной подписки при запуске publi c sub

Question

У меня есть Public Sub, который работает сам по себе. У меня есть два Private Sub на двух разных листах. Каждый из них работает самостоятельно. Но я получаю ошибку на одном из Private Sub каждый раз, когда запускаю Public Sub. Но как только я остановлю код, я все смогу сделать как обычно. Почему при каждом запуске Public Sub возникает ошибка? Вот Private Sub, где я получаю сообщение об ошибке:

Рабочий лист Budget Hours - это то место, где находится Public Sub. Итак, я запускаю его с помощью кнопки, а затем получаю сообщение об ошибке «Приложение определено или определено объектом» в строке Set rng2 = rng1.Offset(0, Target.Row - 6)

Еще одна странная вещь. Мои последние несколько строк кода в Public Sub следующие:

    Application.ScreenUpdating = True

    Columns("B:AA").AutoFit

    Range("A10").Select

    Worksheets("Schedule").Range("E1:E311").SpecialCells(xlCellTypeVisible).RowHeight = 12

    Sheets("Schedule").Protect
End Sub

Он запускает Autofit и .Select даже при выдаче ошибки, но не запускает .RowHeight или .Protect.

Почему он выдает ошибку каждый раз, когда я запускаю Public Sub, даже если каждая часть сама по себе работает нормально?
