Normal Bubble-Up
Error handlers such as On Error Resume Next do not need to be implemented in every procedure written in Visual Basic. When errors are encountered in Visual Basic Scripting Editing, they bubble-up through the call stack until an error handler is found.
In a scenario where there are nested procedures, the error will move up the procedure hierarchy and look for the first error handler. For example, if function A enables the On Error Resume Next error handler and calls function B, which does not contain the On Error Resume Next error handler, and an error is generated in the function B, the error will bubble up and the next line of code in the function A will be called.
