I am having the same problem. I have a grayed out the next button - with an image. I have two hyperlinks that the user must click on to make the Next button available. I have created an action for each hyperlink that modifies a variable. I have an action that should fire when both of the hyperlinks have been clicked and those variables modified that hides the grayed out version of the Next button. Unforunately this is not working, any help would be greatly appreciated.
Thanks
