Scores in database are update sometimes with same function

Hi!

I have a game that work with a database saving scores. I use AJAX to send request and update the scores to database, but i have a problem. The score only update sometimes, not all times in same conditions (same function).

Whats happens, server problem?, construct 2 problem?, ajax problem?.

I save the scores (send ajax request) when construct 2 sum a value a global variable score.

Any idea?

thanks

seems only update when the game run for first time, bus when i lose and restart layour to new game, nos save score.

How can fix that?
