Gene project
Each of the gene infoboxes on WikiDoc display "VALUE_ERROR (nil)" at the top instead of the gene name followed by answers obtained from WikiData for each entry.
Compare ZSCAN21 on WikiDoc with ZSCAN21 on Wikipedia.
Source of the Error
The {{Infobox_gene}} template calls Module:Infobox gene which in turn calls WikiData using local ref_url = "https://www.wikidata.org/wiki/".
The reason none of the gene inboxes work is that Module:Infobox gene here is the same as Module:Infobox gene on Wikiversity or Wikipedia which both work. In short, WikiDoc is outside the WikiData WMF project computers.
Solutions
In order to produce functional gene Infoboxes the Module:Infobox gene needs to be re-programmed to call the original sources of the information to have it appropriately displayed.
Some changes along these lines have been introduced into the Infobox gene for Alpha-1-B glycoprotein, which is of interest to me. Constructing the Species Human Mouse table for inclusion has hit a template snag here on WikiDoc.
