I have this piece of code that I am trying to work, getting HTML validation error.
Print "<td><a href=/content/mark.php?vendor_id=$vendor_id&mark_id=".$_SESSION['mark_id'].">"; echo $mark_name; "</a></td>";
The error that I am getting is on href, that I should have " around /content/mark.php?..., after href=
I tried to concatinate but not getting the logic how to make that work.
