I can see that the map is not updating with a new value entered. I have checked the code in your wagmp_map_1.php page and I can see that you are setting the values based on session variables. It would seem to me that these session variables are not getting the new values to be set properly and are instead just retaining their earlier values. You should take a look at your script that is setting these session variables and do some testing there to ensure that these variables are getting updated properly with the newly posted info.
