I have attached a sample workbook that shows a similar scenario, using two sheets on one dashboard with actions. By clicking on a state the action will narrow the list of customers who have sales in that state. I have included instructions in the workbook.
Hope this helps!
Thank you so much!!!!! That worked beautifully. I think I need to spend some time familiarizing myself with actions!
After clicking on the drop down menu of a selected view on a dashboard (little triangle at the top right corner of view heading), an option is available called "Use as Filter". All other views will be applied a filter based on the dimensions used in the filtering view. To exclude a view from being filtered by another view, there is the complementary option called "Ignore Actions".
