Run A SP With A Datetime Interval From A Table

Hello,

I have something i called a deletelist, inside this list is items that is waiting to be deleted.

The deletelist looks like this:
username nvarchar(20),
itemtype int,
deletedate datetime

The SP that runs once everyday and deletes post is called Data_DeleteFromDeleteList.

Inside of this SP i have afew delete functions like this one:
DELETE FROM reg_user WHERE (username = (SELECT username FROM data_deletelist WHERE (deletedate < getdate() AND itemtype = 0)))

Now i want to add a new delete function to this list, this function is to execute a SP when the itemtype occurs, like this:

SELECT EXEC [dbo].[Data_CompletlyDeleteAUser] @UserName = username, @QResult = @QResult OUTPUT FROM data_deletelist WHERE (username = (SELECT username FROM data_deletelist WHERE (deletedate < getdate() AND itemtype = 2)))

any idea of how i can rewrite this function so it works??
in this SP im not using the @QResult for anything, thats in another SP

At the end of this SP, i just delete all the old records from the deletelist like this,

DELETE FROM data_deletelist WHERE (deletedate < getdate())
