When you use the Cite While You Write function in Word, electronic codes are attached, linking your EndNote library to your document. These codes, called Field Codes, often interfere with publisher's software, so need to be removed before you submit your manuscript online. The process is easy, but permanent.
Another reason to remove field codes is to correct formatting errors made by EndNote when generating a citation.
