>From the description of what you have attempted, it sounds like you are at least somewhat comfortable with some simple programming techniques... If that is the case, then I suggest that you use http://www.TiddlyTools.com/#InlineJavascriptPlugin then, you can write something like this: <script> var tids=store.getTiddlers('title'); var count=0; var total=0; for (var i=0; i<tids.length; i++) { var d=store.getValue(tids[i].title,'cost'); if (d) { count++; total+=parseInt(d); } } if (count) return total; </script> Note: use of 'store.getValue()' assumes you are using a 'custom tiddler field' to hold the data. If you are using a 3rd-party plugin, such as DataPlugin, then you will, of course, need to use the appropriate plugin-defined function to retrieve the data value from the tiddler. Nonetheless, the rest of the above code should be the same. enjoy, -e Eric Shulman TiddlyTools / ELS Design Studios --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
