Pass variables to mailto:

Hello,
I’m trying to create a form that allows users to e-mail their city officials from their own mail client, based on what city they choose to e-mail.

In this form, users would click checkboxes with the people they choose to e-mail, and would enter their name and address information. When they click submit, the variables will be placed into the e-mail below.

Here is the code I’m using to send the e-mail out. The [variables] are the ones that I want populated.
