Displaying percentage value in webi

Hello All,

in my webi document i want to display  a value(percentage of nuber of positions)..i need it in format  as below

1. 88.5%

2. 100%

but the output i get is  155,300

In the Number format....the available format types are  Default, Number, Currency, Date/Time, Boolean, Custom...

its taking "Default ".....i  selected format type as number and  clicked on Custom under the avilable list boxes i gave

#,##0[%]%  and #,##0%  but its not working.

Can anyone tell me how to get the desired format...like  88.5%.

PS : i am working on OLAP universes, the output in bex is of the format 88.5%.
