Quick tip If you get your number into a variable you can then use the sign operator <https://tiddlywiki.com/#sign%20Operator> you could then have two or three css classes defined and have a filter determine which of these three css classes to apply to the display of the number, or use the result of the sign in a list fillter, reveal widget etc...
Untested thinking here <$set name=cssclassname filter="[<number>sign[]match[-1]then[red-bold]else[black]]"> <span class=<<cssclassname>>><<number>></span> Tones On Tuesday, 11 May 2021 at 07:04:04 UTC+10 [email protected] wrote: > Hi!
