How to Set Up Website Field for CustomPress

Hello,

I'm trying to get the hang of using CustomPress. For example, I want to have some custom fields for the Directory plugin such as a click-able web address. It must also be set up so there are no malicious code inserted in the field. Ideally I'd like to allow people to set these up on their own. I have found an expression that I used in "Custom Fields" tab which shows a web address but is not click-able.

I used this: ^((http:\/\/www\.)|(www\.)|(http:\/\/))[a-zA-Z0-9._-]+\.[a-zA-Z.]{2,5}$

Any more experienced people with this knowledge that can help me out?
