We are adding more detail now. You will use two line items one from each module for this filter set up. The desired result has the end user selecting any month or months that they would like from the monthly time settings module published on the dashboard. The chart will then show all of the weeks that are in the selected month based off of a line item in the weekly time settings module. You will need to write a formula in the weekly time scale module to pull this. In the end, you will need to filter the chart by the weekly time module and then publish the monthly time settings module.
The changes to the course will be up shortly. Thanks for bring this to our attention.
