Issue using _datetimeformat to add date to filename and email@!

Hello Everyone,

I could really use your help; I have been working on this for a couple of weeks and have been stuck.  First off I am on a Windows 7 machine 64 bit and am trying to accomplish the following:
>Open up excel file from network drive....then update all (roughly 29) Sql queries in the workbook.
>Save the workbook as ("NewDashboard 1/2/2012.xlsx) with the date in short format
>and email it to the necessary people within the company
>I have gotten it to work with the _DateTimeFormat however it doesnt seem to want to output in the short format and I have checked my regional settings and all of that however no luck.  When I change the $type from a 1 (which is the only thing that currently works to a 2 for short format it gives me an error stating," The requested action with this object has failed."
Here is my code:  Please please help me out guys!
