you are getting more than 1 rows for TotalAmount in tblClientBenfitesForEmployee

SQL

select  ER.BUSINESSNAME as ClientName,E.EMPLOYEE_FIRSTNAME+' '+E.EMPLOYEE_LASTNAME as EmployeeName,

        ISNULL((select Top 1 TotalAmount from dbo.tblClientBenfitesForEmployee where  EmployerID=7 and SupportedID=1 ),0) as Advance,
         ISNULL((select Top 1 TotalAmount from dbo.tblClientBenfitesForEmployee where   EmployerID=7 and SupportedID=2),0) as Child,
          ISNULL((select Top 1 TotalAmount from dbo.tblClientBenfitesForEmployee where  EmployerID=7 and SupportedID=3) ,0)as Health
             from dbo.tblAssignEmployeesToClients  AEC
             inner join dbo.EMPLOYEE_DETAILS E on AEC.EmployeeID=E.EMPLOYEE_ID
             inner join dbo.EMPLOYER_REGISTRATION ER on AEC.EmployerID=ER.EMPLOYER_ID
             inner join dbo.tblClientBenfitesForEmployee CBF on AEC.EmployerID=CBF.EmployerID
             inner join dbo.tblClientBenfitesList CB on CBF.SupportedID=CB.SupportID

             where AEC.EmployerID=7

Happy Coding!
