I am having a similar issue, I only need to post to the database, i don't need to show results in layout. My problem is it will work once, then the next time I load the page it no longer posts when I submit. I have followed the high scores tutorial and the login one. Both are pretty straight forward.
My ultimate goal is to have it so upon either start up or completion of load of my final end game layout I would like it to post the score to the database without having to hit a submit button.
I can upload a capx if need be.
Thanks in advance.
