Is it possible (or what is the best method) to use a channel field name that is coming from the outside of a related_entries tag? Like so:
{exp:channel:entries channel="test"}
{channel_field_name} <!-- Works here! -->
{related_entries id="test2"}
{channel_field_name} <!-- This won't work! -->
{/related_entries}
{/exp:channel:entries}
Looks like this topic covered it on the ExpressionEngine Stack Exchange earlier:
