Uploading a revised source document
I downloaded my converted document and have now revised the source document. I was told by someone on the Lulu support team that uploading a revised document would not cause me to lose my ISBN. When I click on "Revise" on the first document I uploaded, I go back to the Publication Wizard. There is no option to upload my revised document without deleting my project and losing my ISBN. I know it's probably something I'm missing, but how do I upload my revised document without losing my ISBN? Thanks in advance.
