And here's a demo: cpashow.tiddlyspot.com/#How to pass a filter count to a

title: $:/_cpa/macros/filterCount.js
type: application/javascript
module-type: macro

(function(){
/*jslint node: true, browser: true */
/*global $tw: false */
"use strict";
/*
Information about this macro
Returns the count of rows returned by a filter.
*/
exports.name = "filterCount";
exports.params = [
{ name: "filter" }
];
/*
Run the macro
*/
exports.run = function(filter) {
if(filter) {

}
})();
