Problem with setting a Hyperlink to DataTextFormatString of RadioButtonList Control

[AndyASPVB]

Hi I have a radiobuttonlist control on my control, where the datasource is a collection, and I am using the DataTextFormatString to set the text field to a hyperlink. All this bit works, but where I am struggling to work is to add to the url path the value from the datavaluefield. Nothing I try works! Does anyone know how to set the datavaluefield into the url? Further, and one last question, my radiobuttonlist control is in a wizard step, and when the user clicks on a hyperlink, I want it to go on to the next step, all that is happening is that the link is going back to the first step. How do I correct this?
