Question

I have successfully loaded the muscleName items into a table view but am not having any luck loading their respective exerciseName into the 2nd table view.

The method I am using is:

    cell.textLabel.text = [[self.exerciseArray objectAtIndex:indexPath.row] objectForKey: @"exerciseName"];

Maybe I need to define constants?

Edit:

Here is the code in ViewDidLoad for the first table that loads muscleName:

if (muscleArray == nil)
{
    //Read the plist file into an array (the root element is an array)
    NSString *path = [[NSBundle mainBundle]pathForResource:@"test" ofType:@"plist"];
    NSMutableArray *rootLevel = [[NSMutableArray alloc]initWithContentsOfFile:path];
    self.muscleArray = rootLevel;
    [rootLevel release];

Here is my current sub table class

 import "SpecificExerciseTableViewController.h"
    #import "MusclesTableViewController.h"
    #import "CurlAppDelegate.h"
    #import "DetailViewController.h"

    @implementation SpecificExerciseTableViewController
    @synthesize exerciseArray;

    - (id)initWithStyle:(UITableViewStyle)style
    {
        self = [super initWithStyle:style];
        if (self) {
        }
        return self;
    }

    {
        [exerciseArray release];
        [super dealloc];
    }

        // Releases the view if it doesn't have a superview.

    }

            NSString *path = [[NSBundle mainBundle]pathForResource:@"test" ofType:@"plist"];
            NSMutableArray *rootLevel = [[NSMutableArray alloc]initWithContentsOfFile:path];
            self.exerciseArray = rootLevel;
            [rootLevel release];
        }

        // Uncomment the following line to preserve selection between presentations.

Without seeing more of your code, it looks like you’re accessing the exerciseName property okay if you are starting at exercises.
Are you sure that self.exerciseArray is pointing to your exercises object? The quickest way to check is just drop in an NSLog() statement and see if you have what you think you have:

NSLog(@"Exercises: %@", self.exerciseArray);
