I’m modifying a page for a client in an [ASP.NET](http://ASP.NET) page (using [VB.NET](http://VB.NET)), where there is an HTML textfield where a user can put in a “promo Code” to get a discount on a product. When I initially declare the variable, it is set to “radio”. How can I make so that the user can type the code in all capitals, all lowercases, or a combination of the two (basically making it case-insensitive) and the discount will still work?

Thanks
