CDO Mail Object

I have an E-mail ASP Web form that is using a CDO Mail
Object. This form has to be filled out before the
customer can download our demo. Currently, the customer
fills out the form, clicks to submit and a message appears
to the customer telling them it was successful and to
click on a picture on the form to download the demo. My
problem is that many of the customer don't read the
message. I want to modify the code so that after the
customer clicks SUBMIT, the info is submitted and then the
download immediately begins without them having to take
further action.

What is the code I should add to begin downloading a file
after the form is successfully submitted. Here's some of
the code I am currently using:
