I am trying to connect to a database named "login_db"

login_db has 1 table named "accounts"

accounts has 3 fields "id" "name" "pass"

three records were inserted so the database wouldn't be blank.

I am using Flash CC, AS3, PhP, AMFPHP, UwAmp, PhPMyAdmin.

the error i get if i run the swf with ctrl+shift+enter

Attempting to launch and connect to Player using URL L:\UwAmp\www\Databasetest\databasetest.swf
