Problem med inner join....

Har denna sql

<%
	annonsid = Request.Querystring("strannonsid") 
	Forsalj_ID = session("Forsalj_id")

	Set objConn = Server.CreateObject("ADODB.Connection")
	objConn.Open "driver={Microsoft Access Driver (*.mdb)};dbq=c:\crystal\databas\annonser.mdb" 
	SQL = "SELECT * FROM bilannons as a inner join forsaljare as k on a.Rs_forsalj_ID = k.Rs_forsalj_ID WHERE a.Rs_ID = " & annonsID & " AND k.Rs_Forsalj_ID = " & Forsalj_ID & ""
	Response.Write " " & SQL & ""

	set rs = objConn.Execute(SQL)
	%>

Får följande fel meddelande

SELECT * FROM bilannons as a inner join forsaljare as k on a.Rs_forsalj_ID = k.Rs_forsalj_ID WHERE a.Rs_ID = 217 AND k.Rs_Forsalj_ID = 215
