## Steps

1. Start by creating a source table to store all your raw data points.
2. Next, create a target table where your rollup will display summarized data from the source
3. In your target table, click the + icon to add a new column that will connect to your source
4. Select 'Linked relation' and choose your source table to establish the data connection
5. Time for the rollup! Add another column by clicking the + icon in your target table.
6. Select 'Formula' as your column type - this is where the magic happens
7. Now, construct your rollup formula using the linked relation to reference and aggregate data.
8. Voilà! Your formula column now displays the rollup results automatically
