thanks Eric.
I was using action-listops as I've found it in another thread and didn't
know that action-setfield could write in datatiddlers.
I wish I've read your answer before !
in the mean time I managed to use action-listop with this
\define makeAction(tiddler, number)
<$action-listops $tiddler="$tiddler$" $index="latest" $filter="=$number$"
/>
<$action-listops $tiddler="$tiddler$" $index=<<now YYYY0MM0DD>>
$filter="=$number$" />
\end
\define save(tiddler)
<$macrocall $name="makeAction" tiddler="$tiddler$"
number={{$tiddler$##tmp}} />
\end
<$edit-text tiddler="weight" index="tmp" tag="input"
type="number"/><$button>
<$action-listops $tiddler="weight" $index="latest" $filter={{weight##tmp}}/>
<<save weight>>
record
</$button>
weight -> {{weight}}
weight##latest -> {{weight##latest}}
