i was certain i had solved this one rather quickly, but i get the wrong answer. i am new to dynamic programming and any clues on how to debug this would be appreciated.

the problem:

In the 5 by 5 matrix below, the minimal path sum from the top left to the bottom right, by only moving to the right and down, is indicated in bold red and is equal to 2427.

131 673 234 103 18

201 96 342 965 150

630 803 746 422 111

537 699 497 121 956

805 732 524 37 331

Find the minimal path sum, in matrix.txt (right click and 'Save Link/Target As...'), a 31K text file containing a 80 by 80 matrix, from the top left to the bottom right by only moving right and down.

my code:

the problem must be somewhere in the try block.
