sql server - Subquery returned more than 1 value while executing stored procedure -

i have stored procedure this:

alter procedure [dbo].[driverperformance]      @ecode nvarchar(50),      @startdate datetime,      @enddate datetime begin     declare @date1 datetime = convert(datetime, @startdate + ' 00:01:00.000', 120);     declare @date2 datetime = convert(datetime, @enddate + ' 23:23:59.000', 120);     select  e.ecode         ,   cast(q.dtime date) date         ,   e.ename         ,   count(q.ecode) cntecode         ,   (                 select count(*)                 transaction_tbl                 dtime >= '' + @date1 + ''                     , dtime <= '' + @date2 + ''                     , delecode = @ecode                 group cast(dtime date)             )     employeemaster_tbl e     join transaction_tbl q on e.ecode = q.ecode     q.ecode = @ecode         , dtime >= '' + @date1 + ''         , dtime <= '' + @date2 + ''     group         e.ecode     ,   e.ename     ,   cast(q.dtime date)     order cast(q.dtime date) end 

while executing query getting error this:

subquery returned more 1 value. not permitted when subquery follows =, !=, <, <= , >, >= or when subquery used expression.

in query have :

(     select count(*)     transaction_tbl     dtime >= '' + @date1 + ''         , dtime <= '' + @date2 + ''         , delecode = @ecode     group cast(dtime date) ) 

as column. above because of group return more 1 rows each row of select. not posible in sql.
