    Default Re: Problem with tables !

    For future reference, please use the code tags.

    What do you think that exception means? Did you go to the line where the exception is being thrown and look at what might be causing it? Add some println statements prior to the line the exception is being thrown on to evaluate what could be causing it

    I suggest Googling the exception although it is pretty self explanatory.

    Array Index Out Of Bounds....
