To clarify what I was requesting in my last post was some info about the directions map you have on the page. When you create a map and include directions you must enter values for the starting location, or use the bindings to set them dynamically. How have you configured this part of the Map? You can edit the map and get to the last page in the wizard to see this information. I'm assuming that the info is either not correct or is referencing dynamic values that have not yet been set.
As for the other issue with the login were you able to get the new code I posted added in and test the page again? I will need to know the results of the test you performed to continue troubleshooting the issue.
