Conditional display of URL

I have a form where people can pick a charity to which they want to donate, as part of an event booking registration form. I have the charity as radio buttons. When the user selects one, I want to display as a clickable link the URL of that charity's as a conditional field enabled by the radio button selection. Can this be done?

And while I am here, is it possible to add plain text in the registration form? For example, if I wanted to add something like "Delivery of your t-shirt may take from 6-8 weeks:, under the "t-shirt size" text box, can I do this?

You should be able to use a [Field Type -> MESSAGE] custom field for both of these. Put your text / html in the [Description] box, set up your conditional dependency, and your set

Thank you, James, for the quick and precise reply. That did the trick!

Glad I could help
