Hey, Coda —
The substitution in your example there *should* work fine, so I suspect the
trouble lies elsewhere. For example, this works:
\define testSearchBar(field)
<$if value={{$:/temp/search!!$field$}} match="yes">
Search is "yes"
</$if>
\end
<<testSearchBar text>>
Remember that a macro can't define *only* the opening tag of a widget; it
needs to define the content and closing tag as well...
