Setting Up Live Wallpaper with Tasker

I'm trying to set up a Tasker widget to switch between a static wallpaper and a live wallpaper. I have no problem with coming up with the action for the static wallpaper, but I am unable to change my wallpaper for the live wallpaper. Hope someone with experience could help me out here. I am using the latest version of Tasker and the live wallpaper I wish to set up is Koi Live Wallpaper running on a rooted 4.3 stock rom Samsung S3. Thank you in advance.
