PeriodsToDate with Parameter in SSRS

Question

I have the following MDX query in SSRS:
  SELECT 
 NON EMPTY 
 { [Measures].[Gross Premium] } ON COLUMNS, 
 NON EMPTY 
PeriodsToDate([Date].[Date Hierarchy].[Year],[Date].[Date Hierarchy].[Quarter].[Qtr 3 - 2013]),
 [Broker].[Master Broker Name - Big 6].[Master Broker Name - Big 6].ALLMEMBERS ) } 
 ON ROWS 
  FROM [Broker Premium]
However, I need to change the Member Expression in the PeriodsToDate function to use a report parameter value.
If I try this:
  SELECT 
 NON EMPTY 
 { [Measures].[Gross Premium] } ON COLUMNS, 
 NON EMPTY 
PeriodsToDate([Date].[Date Hierarchy].[Year],@DateQuarter),
 [Broker].[Master Broker Name - Big 6].[Master Broker Name - Big 6].ALLMEMBERS ) } 
 ON ROWS 
  FROM [Broker Premium]
It tells me that it expects a member expression for the 2 argument.
is there a way to do this in SSRS?
thanks

thanks David,
that worked, however i then had to add another parameter to constrain the dataset and I keep getting a "failed to retrieve data for report" error.  I think it may be my syntax:
="SELECT " +
 " NON EMPTY { [Measures].[Gross Premium] } ON COLUMNS,  " +
 " NON EMPTY { ( PeriodsToDate([Date].[Date Hierarchy].[Year],strtomember("""+Replace(Parameters!DateQuarter.Value,"Quarter", "Date Hierarchy")+""")), " +
 " [Broker].[Master Broker Name - Big 6].[Master Broker Name - Big 6].ALLMEMBERS ) }  " +
 " ON ROWS " +  
 " FROM ( SELECT ( STRTOSET(""" + "{" + Replace(Join(Parameters!Broker.Value, ","), "Policy", "Master") + "}" +", CONSTRAINED"+""") ) "
+
 " ON COLUMNS " +
 " FROM [Broker Premium])"
i had to use the Join function since the Broker parameter can have multiple values.  Also had to replace the word 'Policy' with 'Master'.
Any ideas?
