Recovering multiple citations by record number within an EndNote 20 database

Leanne, thanks for the reply. Though I haven’t gotten to the point of uploading and downloading sets of references, I did make notes on your suggestion and will keep this in mind when moving references around. With respect to my main question, I think I may have not stated it clearly. I’ve attached a .JPG image to show you an example of what I’m trying to do and what was a routine, straightforward operation with Reference Manager. When I submit a string of references to search for within my database using the Record Number as their search criterion, EndNote tells me the reference(s) is not found. However, if I list each of the same Record Numbers into a separate search lines the system will find every citation l entered. Is there a way to make what I’ve shown in the attached image work within EndNote 20?
