Sum Form to display another Form

Sum Form to display another Form

I have two Forms - in one, the User inputs Daily Sales, Labor, and other figures. In the other form, the User inputs Supply ordersm broken down by Food, Paper, etc. User can input more than one Supply Order a day.
 
I want a View that shows me the Daily Sales, Labor, and Total Supply Amounts for that day. How do I sum the Supply Amounts and add that to the Daily Sales Form?
 
Thanks, Kim
