Simple Error handling in Excel VBA -

i need simple error handling code small macro, have search web have nothing simple, seems complicated.

i down load sales reports in .txt form on weekly basis, run separate macro stuff , add master page. not every week sales reports download there may not have been sales particular region.

i need simple error handler if not find report, moves next sub.

any appreciated

sub mxm_pos()      workbooks.opentext filename:="c:\users\903270\documents\excel\mxmpos*.txt"      ‘run macro code      run ("dlk_pos")  end sub 

here simple basic structure can expand on needed:

sub mxm_pos()     on error goto errhandler      ' code here  exitsub:     ' shutdown code here     exit sub  errhandler:     if err.number <> 0         dim mbr vbmsgboxresult         mbr = msgbox( _             "error #" & err.number & ": " & err.description & vbnewline & _             "would continue?", vbexclamation or vbyesno)          if mbr = vbyes resume exitsub         application.quit     end if end sub 

when desire stack dump construct within source property of err object using concatenation newline, , display msgbox result @ top of calling stack, either event handler launched code or top-level macro invoked user.
