Just to get used to it do the following...
Use the ninja kitty wizard and make 1 analog input as a Tempature Sensor.
Then when it's all said and done, go to the top and click "Behind the Scenes Logic" the Icon with the gears. In the lower right graphical window you will see tabs with your Analog input(s). Click the correlating tab and then click the "Paper and Pencil" icon for Edit Logic Statement.
This is where I got lost for hours and would not have known what to do had I not found a post on here.
Over to the left click the "Add an already programmed function, and click Celcius to Fahrenheit. You'll see the Icon on the layout now, I believe this where you have gotten to. Put it between the the temp sensor logic icon and the output Green arrow icon, then link the nodes. To link the nodes. "Right Click a node, then left click the node you wish to connect it to. It should work. Once your nodes are connected that's it..Save it and continue. They should work.
