How do I get parameters into a query which can't be viewed in Design view?

I've got a query which I can only see in SQL view as Access can't represent the join expression in design view.   I want to add to it a date parameter so it only includes results within two dates which the user types into a form called frmDateFilter, but I'm not sure of the syntax to get it into the code since I normally just add the parameter text below into the design view of a query:

Between [Forms]![frmDateFilter]![txtStart] And [Forms]![frmDateFilter]![txtEnd]

SELECT count(tblClientDetails.clientID)
FROM ( (tblClientDetails INNER JOIN tblEpisodeDetails ON tblClientDetails.clientID = tblEpisodeDetails.ClientID) INNER JOIN 
                       tblAudit as Audit1 ON tblEpisodeDetails.episodeID = Audit1.EpisodeID) INNER JOIN
                       tblAudit as Audit2 on tblEpisodeDetails.episodeID = Audit2.EpisodeID and Audit1.[Date] < audit2.[Date]
WHERE Audit1.TotalScore > Audit2.TotalScore
