Making an array from a plist issue - file-io

Question

First, a little background. I am trying to make a platform game. In front of the game layer I want "lights" to go by and by lights I mean white triangles. I am trying to get coordinates for the triangles from a plist.
At this point I have spent days trying to get my app to read from a plist and I cannot get it to work.
This is what I currently have and this is basically what the internet is saying I should have and that it should work.
In helloWorld.h:
NSMutableArray *foregroundLights;
In helloWorld.m
NSString *path = [[NSBundle mainBundle] pathForResource:#"foregroundlights" ofType:#"plist"];
foregroundLights = [[NSMutableArray alloc] initWithContentsOfFile:path];
I have tried formatting the patch every way that I can think of, I have tried using NSSearchPathsForDirectoriesInDomains. I have tried making the plist a dictionary and making it an array. What am I missing?
Here is a piece of the plist. The full one contains 50 arrays of 4 ints.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>root</key>
<array>
<array>
<integer>128</integer>
<integer>68</integer>
<integer>246</integer>
<integer>7</integer>
</array>
<array>
<integer>181</integer>
<integer>84</integer>
<integer>170</integer>
<integer>62</integer>
</array>
<array>
<integer>118</integer>
<integer>51</integer>
<integer>142</integer>
<integer>64</integer>
</array>
</array>
</dict>
</plist>
