How come the depth and temp don't show up on my Garmin 721? They are just blank.

Check the connection of the NMEA 2000 bus at both the transducer and the back of the Garmin.
You can go into Settings and look at the NMEA 2000 setup and see what devices are on the NMEA 2000 bus.

Depth and temp are showing up on the boat's gauges. Go into settings on the Garmin? Sorry, this is my first experience with this setup.

I just have one cable going to the Garmin. No others hanging around. On settings it says no NMEA 2000 devices. Port 2 is empty. I guess I'm out of luck. While I was under there I found a switch for accent lights I didn't know I had!

What temp are you referring to? Air? Water? Engine? In the Garmin settings there are a variety of temp functions, though I thought only one depth setting.
Post a picture of your gauges

Air and water temp. I guess I don't have the proper cables.

For the engine data, did you install an "engine-specific gateway"? See the Garmin site.
