Problem with Element Linking

Hii Expert,

i'm facing a very strange behavior of element linking. I created a element linking from table to chart and written a formula for chart title as

= If Count(Sum([Current Year]))>1 Then

    "All BalanceSheet Items For Fiscal Year = " +UserResponse("Fiscal Year")

   Else

        (If IsNull(Sum([Current Year]))= 1  Then

            "No Value For BalanceSheet Item : " +[Struct.] + " For Fiscal Year = " +UserResponse("Fiscal Year")

          Else

            "BalanceSheet Item : "+[Struct.]+ " , Value = "+Sum([Current Year]))

Note: [Current year] is a delegated measure and [Struct.] is a dimension. I'm working on standard BEX query balancesheet(0FIGL_M30_Q0016).

Used Sum function to resolve delegated measure issue.

  This is working fine in rich client but when i open the report in BI Launch Pad then got error like Warning Formula Evaluation - Error in data set values :# UNAVAILABE. Check Formula defination in this dataset context.

i have also checked the formula and it's fine no error.I also add sum function to resolve the deletgated measure but still same problem

here is the Output of rich client which is working fine

output in BI launch pad which is not working

Your help will be appreciated.

Thanks and Regards
