I opened the "values needed" list and grabbed the first one in the list, Hitachi, opened the Metric Progress of Hitachi and (1) cliked on "+ Add New" (see screenshot at "1").
A dialogue popped up, I added Year 2014, Value "Yes" (which supposed to be "yes") and a URL to a source. After clicking ok, a "Server Error" was reported, see screenshot.
Note that
the URL is already linked to the Source Page_000001485.
