when you try to run the file there should be lines of code that are in red such as the following. There will be likely more than one line of code in red.

1. Public Declare Function SetTimer Lib "user32" (ByVal hwnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerFunc As Long) As Long


You must type "PtrSafe" before the word "Fuction" in each line of code so the line of code looks like this.

1. Public Declare PtrSafe Function SetTimer Lib "user32" (ByVal hwnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerFunc As Long) As Long
