Query / MySQL / Access

I've got a query that works fine when used in mySQL but completely fails
when I try to apply it to MS Access, weird thing is that it is just a copy
of a stored procedure that works fine in the same copy (with the
Request.QueryString replaced by a fixed value) ! Any explaination would be
great, ID is a number BTW :

SELECT page_title,ID,page_content FROM content WHERE ID='" &
Request.QueryString("ID") & "' '

Had a look at aspfaq.com but couldn't find anything that applys.
