Data Getting Truncated As I Insert I.e. Instead Of Inserting Hello It Inserts 'H'

m inserting some data in big-sized field
and small-sized fields, data of varchar type, int's, dateTime, and
others... i am using something called a stored procedure to add data
into a table.. now when i execute the stored procedure my data gets
truncated (although i made the sizes for my fields ridiculously big
like 1000 just in case) for example if i want to enter Jasmine it only
inserts 'J' in the field

I am sure there's something wrong in the stored procedure, and I am
guessing it's a problem of using single vs. double quotes and stuff
like that within my insert statement...
the following is my stored procedure:

CREATE procedure addLabor
@lName varchar,
@fName varchar,
@mName varchar,
@title varchar,
@craft varchar,
@lastFour varchar,
@SSN varchar,
@dateOfHire varchar,
@currentProj varchar,
@status tinyInt,
@project_id int,
@updateBy varchar,
@updateDate varchar,
@address varchar,
@email varchar,
@phone varchar,
@zip varchar,
@myfeedBack varchar,
@ethnicity varchar,
@userID int
as
BEGIN
SET NOCOUNT OFF
DECLARE @newid INT
insert into laborPersonal ( lName, fName, mName, title, craft,
lastFour, SSN, dateOfHire,  currentProj, status, project_id,
updateBy,

updateDate, address, email, phone, zip, ethnicity)
 VALUES
(@lName  , @fName , @mName , @title  , @craft , @lastFour  , @SSN ,@dateOfHire  , @currentProj ,
@status,  @project_id , @UpdateBy, @UpdateDate , @address , @email , @phone , @zip , @ethnicity )
SELECT @newid = SCOPE_IDENTITY()
insert into feedBack
(lID, feedBack, userID, project_id)
values
(@newid ,+'
+@myfeedBack + ',
+@userID  ,
@project_id )
SET NOCOUNT ON
END
GO


When i use 2 single quotes it insert the following string: "@lName" not the actual value of the variable @lName
my exec statement is this:
EXEC addLabor 'Razor', 'Nazor', 'mid', 'Mr', 'Carpenter Forman',
'1234',
'keOWVozC+wmBvaqgkVkZci5y4vFLdTKfZOVG4C6BSN6H2MBP6pdsIWA0SdPAlPJra0EjEj+uXI/kXSiBuwwnKQ==',
'6/27/2005 12:00:00 AM' , 'O.C. Public Library', 1, 3, '3', '7/25/2005
2:38:02 PM', '1233 Shady Canyon, Irvine', '', '', '12345',
'123-12-1234', 'African American', '3'

I appreciate any help or hints
thanks to all
