I feel like this is probably easy, but I'm missing a step somewhere.
I have two dashboards (we'll say Dashboard1 and Dashboard2).
I want to use the worksheets on each dashboard as "global filters" - to apply to the other dashboard as well. I've set each worksheet to "use as filter" but that only seems to work on the dashboard that it is on, it doesn't affect the other dashboard.
What am I missing? What do I need to do to "hook them up"?
