Hi Merry,
This isn't valid XML/HTML/wikitext:
<$link to=<$view field=birthcountry/></$link>
You can never nest widgets within attributes of other widgets like this
(side note: notice that even if this was allowable, you would be missing a
closing > after the /> to finish the opening $link tag). More generally, it
might be worth learning now that in an attribute like to=, you can do
exactly one of four things in TW:
- to="constant value" [see note 1]
- to={{field transclusion}}
- to={{{filtered transclusion}}}
- to=<<variable transclusion>>
Any combination of these, or any other content, won't work. Here's a summary
of the available transclusion syntax
<https://groktiddlywiki.com/read/#Summary%20of%20Macro%20and%20Transclusion%20Syntax>
.
Fortunately, there's no need to use a $view widget here – you can just
transclude the field with the double-brace syntax:
<$link to={{!!birthcountry}}/>
[1] There are three other ways you can quote the value: """triple
quotes""", 'single quotes', and sometimes no quotes at all (if there aren't
any spaces or special characters in the value).
