How to Add a Slicer to a Report?

[perfectreign]

I'm building my first visualization in PowerBI. It will be a dashboard showing the status of various locations. We have contract staff who are assigned to the locations and we need to see at a glance if any location has less than the required staff, and possibly how much less.  

I can get the report working the way I want, but want to be able to select the critiera for the report. In this instance, I work for an election administration department. I want to be able to select which election to view.  That way I idon't have to update the report for each election.  

I've looked up slicers but can't seem to figure out how to get one on the report. I have teh data for the current election but want a slicer so that I can choose a different one.  How do I do this?

Here's a sample. You can see the report has the data. At the top, I've dummied up a slicer with the election selection I want.  How would I get the slicer to show the information then pass it to the query?

Do you have data for other elections? The slicer just uses columns of data from your report, so you need to have the column in your dataset in order to use it on a slicer.

Thank you! That's kind of what I was thinking.  Now - in this case, it may be a different query.  Let me check how to put two queries into one report. (I wish this was a SQL Server backend but it is an Amazon one, so don't have stored procedures.)
