What does it mean, File must be saved as

[captainjack]

When I start my workflow in Lightroom 3 select my best and delete the rubbish
then start to work on an image as much as I can in Lightroom and the select Photo/edit in, edit in Photoshop CS5 (so still a raw file)
I then finish all my editing on that image and try to save it as a Jpeg
I always get FILE MUST BE SAVED AS A COPY WITH THIS SELECTION
I don't get this come up if I save it as a Tiff or any other save option

Any idea what to means and why It happens

Thankyou for all help and advice

With 'Edit in Photoshop', you shouldn't do Save As. When you've finished with the photo in CS5, just click Save, then exit CS5. You'll find yourself back in LR3 with your up-to-date edited photo in whatever format you took it into CS as: TIFF or PSD. You can then export your photos as JPEGs from within LR. This is the workflow that the designers of LR set up for you. If you want to go your own way and do a Save As from CS without doing a straight Save, you could end up abandoning all the good work you did on the photo in Lightroom.
