MDX Query Attribtue Dimension

I am creating an MDX data export from an Essbase 11.1.2.2 BSO cube to replace a slow-running report script.  Using the Execute MDX in Smart View to test it.  For the rows, I need the first member to be from the cost center dimension.  The second cell will have the corresponding text from an attribute dimension.  I am having trouble getting the attribute text out.  Can someone help me with the syntax?  What I have so far:

WITH MEMBER [Period].[YTD_CLSExpMonth] AS 'SUM(PeriodsToDate([Period].Generations(1), [Period].[&ClsExpMonth]))'

SELECT

  { ([Actual], [JDE], [&ClsExpYr], [&ClsExpMonth]), 

([Actual], [Final], [&ClsExpYr], [&ClsExpMonth]),

([Actual], [Final], [&ClsExpYrMinus1], [&ClsExpMonth]),
