    if (i%2==0) document.write(“<tr>”);
    else document.write(“<tr class=’yellowrow’>”); // have every row with a yellow background use a loop

    The quotes used are not matching pairs and are not ascii values
    Code:
    document.write(<table border=1 cellspacing=1>);
    Use the characters " and '
    Code:
    document.write("<table border='1' cellspacing='1'>");
