N00b is in ddesperate need of some SQL help with parameters

Question

SO I am trying to create a report that will allow the operator to select an application name (appname from table) which I have working as a ripoff of the AdventureWorks db for passing parameters (stored procedure);
USE [Test]
GO
/****** Object:  StoredProcedure [dbo].[App_Get]    Script Date: 2/19/2015 9:40:58 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[App_Get]
@GetName NVARCHAR(500)
AS
BEGIN
;WITH CTE1
AS
SELECT CAST(('<i><j>' + REPLACE(@GetName, ',', '</j></i><i><j>') + '</j></i>' ) AS XML) CSV
),CTE2
AS
SELECT CAST(i.query('./text()') AS VARCHAR(100))CSV
FROM CTE1
CROSS APPLY CSV.nodes('/i/j') As x(i)
SELECT * FROM ae_apps
WHERE appname IN (SELECT * FROM CTE2)
END
AND I have the script that will allow me to pull the information from the multiple tables;
select ae_login.usrid, ae_login.usrnam, ae_login.fullnam, ae_audit.tsstamp, ae_audit.eventid, ae_agdesc.description, ae_audit.appid, ae_apps.appname
 FROM ae_login, ae_audit, ae_agdesc, ae_apps
 WHERE ae_login.usrid = ae_audit.usrid
 AND ae_audit.eventid = ae_agdesc.eventid
AND ae_audit.appid = ae_apps.appid
order by ae_audit.appid, ae_audit.tsstamp
BUT I do not know how to tie that selected parameter (appname) from the dropdown list.  Essentially I want the operator to select the (appname) and have the report generate the audit information from script above for just that selected (appname). 
Any Thoughts would be appreciated.

Hi cnelsonaa27,
According to your description, you want to add parameter to the report, then users can select an application name from the parameter drop down list when they preview the report, but you don’t know how to tie the dataset and parameter, right?
To achieve the goal, please refer to the following steps:
  1. In design surface, in Report Data pane, right-click Data Sources and click Add Data Source.
  2. Type data source name, select Embedded connection, then type select Type and type connection string, or select a shared data source.
  3.Right-click Datasets and click Add Dataset.
  4.Select Use a dataset embedded in my report, the default name is Dataset1, then select data source you added in step2, then copy the query to Query text box:
select ae_login.usrid, ae_login.usrnam, ae_login.fullnam, ae_audit.tsstamp, ae_audit.eventid, ae_agdesc.description, ae_audit.appid, ae_apps.appname
FROM ae_login, ae_audit, ae_agdesc, ae_apps
WHERE ae_login.usrid = ae_audit.usrid
AND ae_audit.eventid = ae_agdesc.eventid
AND ae_audit.appid = ae_apps.appid
order by ae_audit.appid, ae_audit.tsstamp
  5.Right-click Datasets and click Add Dataset.
  6.The default name is Dataset2, select data source from drop down list, then copy the query used to create parameter to Query text box.
  7.Right-click Parameters and click Add parameter, type parameter name and prompt.
  8.Click Available Values in left pane, select Get values from a query, select Dataset2 from Dataset drop down list, select appname as Value field, select appname as Label field.
  9.Right-click Dataset1 to open Dataset Properties dialog box, click Filters in left pane, click Add button.
  10.Select appname from Expression drop down list, set Operator to =, then set value to [@ParameterName], click OK.
