If you are referring to the code i provided a few weeks back:

How to Create a Wappler Server Action to Save Multiple Days of Data to MySQL

You can easily determine the number of days in a month by creating a custom formatter. Make sure the moment.js framework is added on the page: [Screenshot 2024-10-19 at 23.13.06] Then add this code in the head tags, just before the closing </head> tag: <script> dmx.Formatter('string', 'monthDays', function(val, format) { const date = moment(val, 'MMMMYYYY'); return date.daysInMonth(); }); </script> On the page you can then use: {{query.month.monthDays()}} to get …

Your expression is not correct.
It should be: query.month.monthDays() and not query.month.monthDays().daysInMonth
