Hi Jan, > Calc does not render if the counter-Field does not exist or is empty. >
I could extend calc, so that it would initialize the value when it would otherwise be undefined / NaN, e.g.: <<calc "0=>!!counter" +1>> Meaning: - if counter is undefined / NaN, initialize as 0 - if counter is a number, add 1 You could initialize with a numeric value of your choice: <<calc "7=>!!counter" +1>> I would make it so that whatever is left of "=>" would have to be numeric for the expression to be valid. Would that help? Best wishes, Tobias. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
