I inserted an "Upload for document" hyperlink into my "New Activity" screen so that people could attach documents to certain activities. But now when I export the results of the activity table there's a lot of junk in some rows of the CSV file, and I believe it has to do with the PDFs being attached to the activities.
What do I need to do to attach documents to activities but still be able to use the data from the Activities table. Note that I did not add a field in the activity table for the documents.
