Bubblesort causing runtime error while sorting a dynamically allocated multidimensional character array

[Chinchilla03]

This is a homework problem, but I am completely stumped as to what is causing this error. I have tried searching for a solution online but it is difficult to refine a key word search for this specific issue and has yielded no results.

On to the issue. My code is supposed to read in each word from a .txt file containing the Bill Cosby quote: "I don't know the key to success, but the key to failure is trying to please everybody." It then must store the data in a dynamic two-dimensional array. Once this is accomplished it counts how many times an individual word appears in the quote and then outputs a sorted list to the screen.

My bubblesort is causing a run-time error, and after hours of thinking and going through the code I simply cannot come up with a reason why. It starts sorting just fine until it tries to swap "to" with my placeholder, ",".

Any help is much appreciated, as well as feedback on my posting format.
