I can insert other files from the same location, but when I try to link an object...a pdf...into a container field, I get the message "the action can not be completed because the selected link's source is presently unavailable". However, the word, excel and jpg's are in the same location. What am I missing on the pdf?
Haven't seen that exact error message before. Exactly what steps, and options are you taking to insert this file? Are you confident that the file is at this same location and you don't have a shortcut/alias to this file here instead?
