hi,
I just started using this and I'm not getting ground shadows. I tried turning
them on in SketchUp but it's not working. I tried messing with the code, but I
don't really know what I'm doing. Please help!

Are you exporting a 3d model from Sketchup for rendering in POV-Ray?
You'll need to provide a bit more detail for anyone to help you.

I'm in sketchup and I use the plugin which makes a POV file, I am then in
POV-Ray using that file generated by sketchup to render my image.

I'd check the objects in the POV file for 'no_shadow'.
If it's there get rid of it, if not then I can't say for sure as I know
nothing about sketchup.
But in POV there are only few ways that there are no shadows. Check the
light sources, if there is 'shadowless'in them get rid of it.
If there are no light sources then you will have no shadows!!
And lastly make sure that the objects are on or near the ground.
Some times a combination of camera & object & ground plane placementa
combine to makes it look like an object had no shadow.
Hope this helps.
Have Fun!!

You should also look at your light_source. They may have the shadowless
attribute. You can do a search for "shadowless" if your source file is
to long.
If so, remove that attribute.
shadowless is OK for weak fill lights, not for the main light(s).
Take a look at your ground plane, especialy it's finish block.
Search for ambient and diffuse. Launch a search for "finish" if you
don't find. You may have a finish resembling to:
finish { ambient 1 diffuse 0 }
Whitch create a surface that don't react to any light.
If so, you can do one of the following:
Add a "//" in front to comment out that finish and use the default one.
Or:
Change the finish to:
finish{ambient 0.05 diffuse 0.7}
