help!! i'm working with a two-dimensional array in perl. i originally tested all my code using hard coded data... 
@array = (
           [ "A", "B", "C" ],
           [ "D", "E", "F" ],
           [ "G", "H", "I" ],
    );

then i iterate through my array using a some for loops... 
for($col = 0; $col < $width; $col++)
{
    for($row = 0; $row < $height; $row++)
    {
        $myString = $myString.$array[$row][$col];
    }
        $myString ="";
}

this worked fine until i tried reading from a data file copying the file into an array. when i try to run it i get: 
"Use of unitialized value in concatenation... blah, blah"

i tried splitting the file into lines then elements but nothing seems to work. can anybody help me??? -confused
