Total row like on the Time & Billing template download

[BrookieOU]

I would like to total down a column in a form like in the "Time and Billing"
template you can download from here. On their project list form they have a
row across the bottom that totals the columns. You can click on the column
and choose (Sum, Average, Count, etc). I cannot for the life of me figure
out how they did this. I would like to use the same functionality on another
form but cannot figure it out. I've tried and tried and looked everywhere!
Can someone please help me!

Thanks,
Brooke

Nevermind...I'm an idiot. I figured it out! There is a totals button on the
toolbar!
