OK, thanks. However I don't want to revert to the original, just to open the file as it was when I closed it. The info is still in the 'output' file, but the file is no longer split or selected when I reopen it.
I can rerun the steps, but it seems odd to have to do that. A bit like editing a Word doc, then the edits not saving.
I'm using Windows 8.1, SPSS version 22, and studying psychology. So the data is random stuff, such as using Andy Fields files.
