Access: How to pass parameters to report when WHERE clause is embedded in complex SQL

I know the question of how to pass parameters has been asked a while back with the this Previous Stack Overflow question

However my situation involves SQL that is a bit more complex and cannot make use of the "where clause" filter available when opening a report. My SQL statement is an aggregate that produces a single row with one field for each aggregate. I have two parameters "@StartDate" and "@EndDate" that I need to pass into the query. 

SELECT q1.CasesAssigned, q2.WarningsIssued  
FROM 
(SELECT COUNT(*) AS CasesAssigned 
FROM vwCaseDetail 
WHERE DateAssigned Between @StartDate AND @EndDate) as q1,  
(SELECT COUNT(*) AS WarningsIssued 
FROM vwWarningDetail 
WHERE DateIssued Between @StartDate AND @EndDate) as q2

What I would like to do is "popup" a dialog or small form to have the user enter the Start and End dates but I have no idea on how to pass the values into the query the report is based on. Any suggestions? Thank you.

All you need to do is call the report from a form. On this form you have two text boxes for your start and end dates.

The query then has to be changed to 

WHERE DateAssigned Between [Forms]![frmReporting]![txtDate_from] AND [Forms]![frmReporting]![txtDate_to]
