I'm using SQL Server and I'm stuck on a problem. Any help would be appreciated! 

Using the AP database create a stored procedure called `spFindInvoices` that accepts two parameters: `@NameVendor` of type `varchar` and `@BalanceLimit` of type `smallmoney`. 

This procedure displays the VendorName, InvoiceNumber, InvoiceDueDate and Balance of @NameVendor where the balance is greater than @BalanceLimit. If you call/test the procedure with `@NameVendor = ‘Federal Express Corporation’` and `@BalanceLimit = 0`, the following table will be displayed:

```
(my code)
USE AP;
GO

CREATE PROC spInvoices
     @NameVendor VARCHAR(50),
     @BalanceLimit SMALLMONEY
AS
    SELECT 
        VendorName, InvoiceNumber, InvoiceDueDate, 
        (InvoiceTotal - CreditTotal - PaymentTotal) AS Balance
    FROM 
        Invoices 
    JOIN 
        Vendors ON Invoices.VendorID = Vendors.VendorID
    WHERE 
        @NameVendor > @BalanceLimit
GO

EXEC spFindInvoices @NameVendor = 'Federal Express Corporation',
                    @BalanceLimit = '0' 

```
