        header("Location: admin.php");
}
if($_SESSION["type"]=="admin")
    {
    include("adminmenu.php");
    }
    else

    }

include("footer.php"); ?>

<p><a href="examview.php?first=<?php echo $first; ?>&amp;last=<?php echo $last; ?>"></a></p>

Line 19 and 20. Use $result on both lines.

oops,,the error message is still there..tnx,,for effort,

Check the rest of the code. It's either something similar, or an error in your query. Add error checking to find out.
