Joshua's site says that the improved "indexes" filter will return all paths. So
IF you have the same number of entries for each nested group, then you can divide by that number and add one to get the next number in the sequence: <$list filter="[[myData]indexes[]count[]divide[2]add[1]]" variable="nextnum"> ... do stuff </$list> This example assumes 2 items per group. The problem with this approach is that you might, at some time, delete an entry. So this approach only works if you never delete entries. A more advanced approach would require you to add a "number" field to each nested group. If you had such an index, then you could write a macro that would run through the entries, find the highest value and add one. hth On Wednesday, November 13, 2019 at 11:51:24 AM UTC-8, si wrote: > Thanks for your help, that does the trick. > > In order to get a new numerical value for each level every time I press > the button I have used the MathyThing > <http://inmysocks.tiddlyspot.com/#MathyThing%20-%20action-increment%20Widget> > plugin to increment the number in a field called "number".
