Sorry I'm abusing the MySQL forum. Will mark this as solved and look elsewhere. The "Race condition" opened the door to the real issue here. Thanks a lot.

Thanks for the replies. I see what you mean, but... how does the list() function *wait* until it gets the control variable filled from the insert() function? Sorry I'm pretty new at javascript and AJAX.

Hello, I have a problem with a SELECT that *sometimes* doesn't show the row from a previous INSERT. It fails around 1 call of every 10. The structure I have is the following: 1) HTML button: calls the javascript function insertAndList(). 2) insertAndList(): calls the javascript function insert() which through AJAX executes a PHP that inserts a row in a MySQL databas. 3) inserAndList(): calls the javascript function list() which through AJAX executes a PHP that lists the table. If I add a delay of 100ms between 2) and 3), the list() function fails much less often, around 1 of every 100. Is there a way to force the SELECT to "refresh" the buffer or whatever it is that is showing the old number of rows? (i'm not using MySQL CACHE, as far as I know).
