Help from a sheet to another

Help changing sheets.

Hi, I am starting to use VB, and recently I have a problem with my workbook. I put some buttons to move from sheet to sheet with the following command:

Sheets("Protocolo").Select
End

The problem is that when I use the button to move from sheet to sheet the screen got froze. It won’t let me do scroll down, and don’t let me change the values. I try to fix it using different commands like:

Application.Goto (Activeworkbook.Sheets("Protocolo ").Range("A1"))

Or

Application.ScreenUpdating = False

Or

Application.ScreenUpdating = True

But nothing work. If anyone could help I would really appreciated.
