What operating system do you use?
What version of calibre do you have?
When do you get this error?
If it's when you're defining the column, all you need do is click the blue ISBN at top of the dialogue box and click OK.
If it's when you enter an ISBN in the
Ids: box the Metadata Edit dialogue then you must enter
isbn: followed by a valid
International Standard Book Number - e.g.
isbn:9780691156842
Please capture the error - if is a calibre error it will have a "Copy to clipboard" button, use that and paste the message here, otherwise take a screen shot of the error popup and post it here (use the paper clip icon in the top toolbar).
