Dynamic Crosstab - How To Pass Parameters

I am trying to use one sql store procedure but don't know how to pass the parameters. I am posting here my store procedure:-

create procedure dynamic_pivot
(
@select varchar(2000),
@PivotCol varchar(100),
@Summaries varchar(100)
) as
declare @pivot varchar(max), @sql varchar(max)

[Code] ....

My table looks like below:

emp_id, time_code, date, time_charged
RB, VAC, 20130222, 8
RB, HOL, 20131128, 8
RB, VAC, 20130311, 8

My output should be:

emp id VAC HOL
RB 16 8
