I created the column as you said, I think but I must be doing it wrong because all that shows in the column is:
"Program: list_re(formats_modtimes('yyyy-MM-dd hh:mm:ss'), ',', 'EPUB

.)', '\1')
Is there a check box or switch I missed? Can I change EPUB to MOBI and have it still work.
Sorry I am not a programmer. Thanks
