insert into mysql db

Hvad er der galt her, jeg får en HTTP 500 - Internal server error :

SQLserveradr="xxx"
SQLdatabase="xxx"   
SQLlogin="xxx"
SQLpassword="xxx"



'Set cmdDC = Server.CreateObject("ADODB.Connection")
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open "driver={MySql};server="& SQLserveradr &";database="& SQLdatabase &";uid="& SQLlogin &";pwd="& SQLpassword

Set objRS = objConn.Execute("insert into tblbruger (brugernavn, brugerpw) values ('& username &', '& pass &'")
