Modules & VBA :: Leaving Open Instances Of Excel After SaveAs

I have some code that opens and populates an Excel spreadsheets then does a save as to a specific directory and also outputs a PDF. This code is working with one small problem, I am leaving the first instance of Excel open and can't figure out where I should put the code for it to quit. Here is my code:

Code:
' This code creates a recordset based on the current reservation in order to gather data on
' a specific reservation, to output to a payment schedule excel spreadsheet which calculates
' Payment dates and amounts for specific reservations
' Declare variables for recordset
Dim rst As DAO.Recordset
Dim db As DAO.Database

[Code] ....

The instance that I need to close is shown in red.
