    1. COCan you give us example values for `birthRate`, `deathRate`, `currentPopulation`, and `years`?

    2. CObirthrate and deathrate can be any percentage rate. currentpopulation is just a number for the population. and years is going to determine the amount of time the for loop in the estimatedPopulation function will execute. You want me to actually tell you my input and then results?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
