Dashboard - How to create a metric that will display a Count of data in a column?

edited 12/09/19 in Smartsheet Basics

Good Afternoon,

I am new to dashboards. I am trying to use an existing Smartsheet with data and would like the dashboard to display a count of how many individuals are listed in column 1 on the sheet. Is this possible and if yes, how do I set it up? Do I have to have the count built into the sheet for it to display on the dashboard?

Thank you in advance for any help you can provide.
