Hio,

Back in my code
<ul>
<$list filter="[all[]prefix[New]has[field]]">
   <li><span style={{{ 
[all[]prefix[New]!title<currentTiddler>get[field]match{!!field}then[color: 
red;]] }}}>* <<currentTiddler>> {{!!field}}*</span></li>
</$list>
</ul>


*<<currentTiddler>> {{!!field}} *is the display
replace this with 
*{{{ [all[current]get[field]format:date[]] }}}*
Not tested by me on this occasion

where field is the chosen fieldname.

Regards
Tones
