Hi Mat, It works a little bit too well. The field update is applied everywhere downstream in the hierarchy, not only the level immediately below and not limited to the branch leading down from the current tiddler. So let's say I apply it at level 2. Using only three nested list widgets I was able to apply it five levels down (I didn't look further) and it was also updating tiddlers in other branches. How can I restrict the loop to the tag hierarchy below the current tiddler? Regards, Pall
