Data Getting truncated as I insert i.e. instead of inserting Hello it inserts H

m inserting some data in big-sized fieldand small-sized fields, data of varchar type, int's, dateTime, andothers... i am using something called a stored procedure to add datainto a table.. now when i execute the stored procedure my data getstruncated (although i made the sizes for my fields ridiculously biglike 1000 just in case) for example if i want to enter Jasmine it onlyinserts 'J' in the field
I am sure there's something wrong in the stored procedure, and I amguessing it's a problem of using single vs. double quotes and stufflike 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', '7/25/20052:38:02 PM', '1233 Shady Canyon, Irvine', '', '', '12345','123-12-1234', 'African American', '3'
I appreciate any help or hints
thanks to all
All of your parameters are declared like this:
@.lName varchar,
Should be like this:

@.lName varchar(1000),
a type of varchar is like varchar(1), meaning a variable length string with a max of 1 character. The number used should likely match the underlying length of the field in the table
