Complex Essbase MDX Issue - Need Guidance

Question

Hi,
I have a complex Essbase issue in ASO version 11.1.2.2. Currently I have a MDX formula with a Measure member named '10th Percentile'. It calculates the 10th Percentile perfectly. So new requirement is to create a new Measures member and instead of calculating the '10 Percentile' value, it needs to display the Customer Name of the value that is the 10th Percentile from the Customer dimension. So if I do a retrieval and the '10th Percentile' is 3.23, then it needs to display the Customer Name of the 3.23.
So I altered the formula to do what I think needs to be done and it verifies. However if I retrieve on that new measure in the Excel Add In, I get and error: An error [1200315] Occured in Spreadsheet Extractor. However if I navigate without data I don't get the error, but I also don't get any data, which I obviously need. So my question is, if MDX support reporting on Metadata not just Data, what/how can one report on it? Ideally I need to have this work in the Excel Add In as the client is using a custom vba modified template for their end users.
Any ideas and help?

Here's the formula. I bolded the part that is new.....
IIF ( [Lbs Per Yard].CurrentMember IS [Lbs Per Yard].[No_Lbs/Yd] ,
IIF( [Count_Price] = Missing, Missing, IIF( [Count_Price] < 2 , Missing,
{ Order (
Filter ( CROSSJOIN ( Leaves ( [Service].CurrentMember)
, Filter ( CROSSJOIN ( Leaves ( [Segment].CurrentMember)
, Filter ( CROSSJOIN ( Leaves ( [Customer Type].CurrentMember)
, Filter ( CROSSJOIN ( Leaves ( [Zip Code].CurrentMember)
, Filter ( CROSSJOIN ( Leaves ( [Quantities].CurrentMember)
, Filter ( CROSSJOIN ( Leaves ( [Frequencies].CurrentMember)
, Filter ( CROSSJOIN ( Leaves ( [Yardages].CurrentMember)
, Filter ( Leaves ( [Contract Year].CurrentMember)
, [$/Yd] <> Missing ))
, [$/Yd] <> Missing ))
, [$/Yd] <> Missing ))
, [$/Yd] <> Missing ))
, [$/Yd] <> Missing ))
, [$/Yd] <> Missing ))
, [$/Yd] <> Missing ))
, [$/Yd] <> Missing )
, [$/Yd] /*this is the measure we're using for sort */
, BASC /* sort in $/Yd in ascending order */
) AS OrderedSetOfItems} /* here we define an alias for the set in order to be able to use it later */
.Item ( Round ( Count ( OrderedSetOfItems) *
10 / 100 /*where we specify which percentile is being calculated */
+ 0.5 , 0 ) -1 ) *.Item (3-1).[MEMBER_NAME]*
/* this takes Nth item from the ordered set (0-based index, hence -1) */
/* .Name takes its name */
, Missing )
