I am having trouble saving a spreadsheet.
This spreadsheet has already been copied
I am using the line
    $excel->Workbooks(1)->SaveAs($sp_full)  or ($excel_res = 0, $ew_message = "Could not save spreadsheet <$sp_full>");
To try and find out why I used the following two lines to get the error number and corresponding message
$en_num = Win32::GetLastError();
$en_f = Win32::FormatMessage($en_num);

[download]
I get the error number of 317 but $en_f does not contain anything
I then get a dialog box asking if I want to save the changes to the spreadsheet.
If I add the line, before trying to save, of $excel->{DisplayAlerts}=1;
I get a message indicating that the file is there and asking if I want to overwrite it.
Can anyone suggest why this is happening and how I can cure the problem?
