I'm trying to build a form that members can submit data to which will be calculated and return some results back to them. I don't want them to have to go to a new page, though, to view the results. I'd rather just have the results given to them from a template in an overlay. However, when I do this: PHP: return $this->responseView('Addon_ViewPublic_Index', 'addon_results_template', $viewParams); I just get a message that says "Unspecified Error" and nothing else happens. Is there a class, or something, that I'm missing to make this work? Any help would be greatly appreciated.
