However, it doesn't work when i try to run this code.
``cs
namespace Treehouse
class Cell3
{    
int[][] sheet = new int[10][];
sheet[0] = new int[10];
for(int rowIndex = 0; rowIndex < sheet.Length; rowIndex++)
{
    sheet[rowIndex] = new int[10]; //creata row of 10 cells
    for(int colIndex = 0; colIndex < sheet[rowIndex].Length; colIndex++)
    {
        sheet[rowIndex][colIndex] = rowIndex*colIndex;

}
}
}

:point_right: Do you mean when you "try to compile this code"?
The REPL lets you experiment with code bits that are not a complete program.  To compile and run a program, you'll need to add a bit of "boilerplate", including a class and static Main method to contain the executable part of your code.
