Running Values

Hi,

I want to get unique running value for full name (First_Name, Surname). Below expression is calculating only based on First name alone, even when the full name is passed.

RunningValue(Fields!Full_Name.Value, countdistinct,Nothing)

This occurs only for few names.

For example:

169  Diana Bueno Toro

169   Dianne Cook

I get the full name using the below T-SQL

 RTRIM(LTRIM(ISNULL(prov.first_name, '')))+ ' ' + RTRIM(LTRIM(prov.last_name)) AS Full_Name

Any help is highly appreciated.

Regards,
