i want to add an onclick handler to a link that will throw an alert box that:

1) displays a url for terms & conditions (how do I code a url in an alert box?)

2) prompts the user to enter their name to confirm they have read and agree with the terms & conditions

3) returns false if the prompt field is empty

4) loads the link if the prompt field is not empty

Sorry, I've searched for a solution... but now I need some help from you experts!
