Mark, Why don't use of *range* operator? look at: https://tiddlywiki.com/prerelease/#range%20Operator
This is equivalent to your code. Here you can set the upper range a big number like the last week number: 52 \define nextweek2(thisweek) <$list filter="[range[1,8,1]addprefix[0]] +[after[$thisweek$]]"/> -*Mohammad* -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
