TOPIC: Radio Buttons and Calculations

I'm using DTRegister to create a form for purchasing Online Backup. What I'm looking to do is just have the form as the first step and would include radio buttons to choose what storage package to choose. When the radio button is selected for the type of package it would calculate the cost for that package. Then the user would hit "Next Step" which would direct them to PayPal to complete payment info.

I set it up now so that each package is basically an event. The user clicks on the package which then takes them to the form to fill out their information. I'd rather skip the first step and include the package choice within the form. I was told this would be possible in a pre-sales question, but I'm not sure how to set it up. Here's a link to my site...
