If so:
add as the first line of your script right after the <?PHP
phpinfo();
Run your application, scroll to the bottom and look at the "php variables" and make sure that your are asking for $_GET["Username"] and $_GET["Password"] are what the script sees
If not:
You may have to run just that page with http://whatever/whatever.php?Username=whatever&Password=whatever to see if the problem is in the form or not

I made that.. but there is something strange!!
I SELECTED field from the database.. but it is not showing what it contains!!
This is what is shown on the screen :
UPDATE accounts SET LogoutTime=1075313199SELECT LoginTime,Distance,LessonNumber FROM accounts WHERE UserName='' AND Password=''UPDATE accounts SET LessonNumber=LessonNumber + 1
Query error: You have an error in your SQL syntax near '0') WHERE UserName= AND Password=)' at line 1
So what is wrong!!!??
Everything is inserted and updated correctly in the database.. but the distance is the same.. no changes.. no updates!!
