FILTER Question

 I have a question regarding a FILTER clause in MDX. I have what I think should be okay MDX syntax, but when I try to prepare the query in Query Designer, it just hangs. Is the syntax I'm using correct?

 SELECT 
  NON EMPTY 
    {
      [Measures].[AR INV PAID TO DATE]
     ,[Measures].[AR INV AMOUNT] 
     ,[Measures].[AR INV AGE]
     ,[Measures].[AR INV AMOUNT OUTSTANDING]
    } ON COLUMNS
 ,NON EMPTY 
FILTER
(
    {
        [DIM PROJECT].[Client].[Client].ALLMEMBERS*
        [DIM PROJECT].[Division].[Division].ALLMEMBERS*
        [DIM PROJECT].[Product].[Product].ALLMEMBERS*
        [DIM SALES CLASS].[Sales Class Type].[Sales Class Type].ALLMEMBERS*
        [DIM AR INVOICE].[Invoice Number].[Invoice Number].ALLMEMBERS*
        [DIM AR INVOICE].[Invoice Date].[Invoice Date].ALLMEMBERS*
        [DIM PROJECT].[Job Number].[Job Number].ALLMEMBERS*
        [DIM PROJECT].[Job].[Job].ALLMEMBERS
    } * [DIM INV AGE RANGE].[Invoice Age Range].[Invoice Age Range].ALLMEMBERS*
         [DIM INV AGE RANGE].[INV RANGE ID].[INV RANGE ID].ALLMEMBERS,
        [Measures].[AR INV AMOUNT]  > .01
)
