I have a SQL stored proc called wit_AddAddress:

CREATE PROCEDURE wit_AddAddress
	@AddressTypeKey	INT,
	@Street1	VARCHAR(100),
	@Street2	VARCHAR(100),
	@City		VARCHAR(40),
	@State		CHAR(2),
	@PostalCode	CHAR(10),
	@AddressKey	INT = 0 OUTPUT
AS

BEGIN

	INSERT INTO wit_AddAddress
		(AddressTypeKey, Street1, Street2, City, State, PostalCode)
		VALUES
		(@AddressTypeKey, @Street1, @Street2, @City, @State, @PostalCode)
		
	SET @AddressKey = SCOPE_IDENTITY()	

END

I have verified that this proc is there in SQL. When I run the following C# code, I get the error "Invalid object name 'wit_AddAddress'":

public override bool SaveChanges()
{
    bool RetVal = Validate();

    if (RetVal)
    {
        string ProcName = string.Empty;

        SqlParameter pAddressKey = new SqlParameter("@AddressKey", 0);

        if (this.RecordId == 0)
        {
            pAddressKey.Direction = ParameterDirection.Output;
            ProcName = "wit_AddAddress";
        }
        else
        {

            pAddressKey.Value = this.RecordId;
            ProcName = "wit_UpdateAddress";
        }
       
        SqlParameter pAddressTypeKey = new SqlParameter("@AddressTypeKey",_AddressTypeKey);
        SqlParameter pStreet1 = new SqlParameter("@Street1", _Street1);
        SqlParameter pStreet2 = new SqlParameter("@Street2", _Street2);
        SqlParameter pCity = new SqlParameter("@City", _City);
        SqlParameter pState = new SqlParameter("@State", _State);
        SqlParameter pPostalCode = new SqlParameter("@PostalCode", _PostalCode);

        ArrayList colParams = new ArrayList();
        colParams.Add(pAddressKey);
        colParams.Add(pAddressTypeKey);
        colParams.Add(pStreet1);
        colParams.Add(pStreet2);
        colParams.Add(pCity);
        colParams.Add(pState);
        colParams.Add(pPostalCode);

        AppDataAccess.ExecuteNonQuery(ProcName, colParams);

        if (AppDataAccess.DataException == null)
        {

            if (pAddressKey.Direction == ParameterDirection.Output)
            {
                this.RecordId = Convert.ToInt32(pAddressKey.Value);
            }
        }
        else
        {
            throw AppDataAccess.DataException;
        }
    }

    return RetVal;
}

When called for edits, the reference to "wit_UpdateAddress" works. Like I said, the proc is there. Anyone know why this would be happening????
