    Please use code tags when posting code

    The compiler is complaining about the code on line 35.
    I suspect it's the following line as it's not a legal use of the % (remainder) operator
    Code:
    if(( i % == 1) && (j % == 1))
    I suggest you read a tutorial on how to use the remainder operator
