Question

I need to trigger(return) an error event from a VBA function, then the calling function of this function can trigger On Error Go to call.
E.g

function Test()
 On Error Go to myError:
       TestErr()
 Exit Function

 myerror:
    Test = "Error Triggered"
End Function

Function TestErr()
    ?? 'How to Trigger error here
End Function

Thank You
