Hi, i have been working on this for well over a week now and i just cant seem to get this to work...  What im trying to do is when a member registers, i want to call a php file using javascript and inside that php file it opens another database and increments a value then closes.... 

i have the javascript command in the registration php file but it will not write to the new db when executes the file... is this because you cant have two db open at once or what...

here is the process i have, but its not working...

it calls the php file (using javascript) that belongs to another peice of software located in the same domain.
that called php file uses its own includes to set the database open
then that php file writes the new value to the new database
then it closes and thats it....

is there a better way... what am i missing   i have tried setting up a $link script to test but still does not work...
