User Input of Date as a Query

I have a query which goes like this:

StockAnalytics.uDIX - StockAnalytics.dDIX > 0.5 
    AND (To开发者_StackOverflow中文版day1.uDIX - Today1.dDix) > 0.5 
    AND (Today2.uDIX - Today2.dDix) > 0.5 
    AND (Today1.uDIX - Today1.dDix) > (Today2.uDIX - Today2.dDIX)
    AND (Today2.uDIX - Today2.dDIX) > (Today3.uDIX - Today3.dDIX) 
    AND StockAnalytics.[Date] > @Date    

I am trying to take the input from the user on which date he wants to run the query. When I enter the date, it asks for the same input twice.

Anything wrong with this query?

EDIT: I don't think, I could get my problem across. When I use this code snippet, it works perfectly, except for the fact that, the dialog box, prompting the user to enter the Date, comes twice I don't want to have it pop twice. Only after the user has entered the "date" the second time, does the results come up

If you need to include a parameter twice as in:

 SELECT Stuff
 FROM ATable
 WHERE FirstDate > [Please enter date: ]
 AND SecondDate > [Please enter date: ]

Then include a parameter line:

 PARAMETERS [Please enter date: ] DateTime;
 SELECT Stuff
 FROM ATable
 WHERE FirstDate > [Please enter date: ]
 AND SecondDate > [Please enter date: ]

Or better yet, use a form:

 SELECT Stuff
 FROM ATable
 WHERE FirstDate > Forms!Dates!txtDate
 AND SecondDate > Forms!Dates!txtDate
