Modules & VBA :: Multiple Selection List / Comma Separated String - Run Query And Create Report

I'm using Access 2007.

So far I have a Multi Select enabled list on which the user selects the serial numbers they want. They then click the "Report" button which will trigger a query based on the selected serial numbers to create a report on those serial numbers.

I have the code for the multi-select list working already. It creates a string of comma separated values that are the serial numbers which are selected in the list. Somehow I need to pass this string to my query so it can use it as a filter.

Here is some of my code:

Code:
Option Compare Database
Option Explicit
Private Sub Form_Current()
Dim oItem As Variant
Dim bFound As Boolean

[Code] ....

Here's my current query in SQL:

Then finally how to I get the query to execute and create a report based on all of this?
