Visual Basic for Applications Reference Visual Studio 6.0 on error resume next example On Error Statement See Also Example Specifics Enables an error-handling routine and specifies the location of the routine within a procedure; can also be used to disable an error-handling routine. Syntax On Error GoTo line On Error Resume Next On Error GoTo 0 The On Error statement syntax can have any of the following forms: Statement Description On Error GoTo line Enables the error-handling routine that starts at line specified in the required line argument. The line argument is any line label or line number. If a run-time error occurs, control branches to line, making the error handler active. The specified line must be in the same procedure as the On Error statement; otherwise, a compile-time error occurs. On Error Resume Next Specifies that when a run-time error occurs, control goes to the statement immediately following the statement where the error occurred where execution continues. Use this form rather than On Error GoTo when accessing objects. On Error GoTo 0 Disables any enabled error handler in the current procedure. Remarks If you don't use an On Error statement, any run-time error that occurs is fatal; that is, an error message is displayed and execution stops. An "enabled" error

Be very cautious using it. –Nate Feb 4 '10 at 20:22 2 It makes more sense now. After some functions that can end up in error.

Error handling is an important part of every code and VBA On Error Statement is an easy way for handling unexpected exceptions in Excel Macros.
