VBA Radio Buttons and Options

I'm looking to use two radio buttons 1. 'Yes' and 2. "No. Basically what I'm trying to do is if in an order form if a certain minimum monetary value is not met the extra monetary value is added to bring it up to the minimum.

I was just wondering how do I go about writing this in VBA?

Many thanks

So where do the radio buttons come into it...? Either the order is greater than the minimum value or it's not...

I want a user to click the radio button stating whether the minimum amount has been met.
