Division by 0 (zero) in an App

Well, I tried your above suggestion.
App Name: HeatIndex
Inside App: EXPORT Heatindex()
Go to home screen
Select: Toolbox, then App, then HeatIndex->HeatIndex
I now have HeatIndex on the command line
I hit Enter. App does not start. All it does is shift HeatIndex above the command line and displays 0.0000
It does the same thing if I use HeatIndex().
It also does the same thing if I take the divide by 0 out of the App.

Am I doing something wrong?

Was the app designed to start using the HeatIndex() program? In other words, how do you normally start your app? Usually, apps are "run" using one of the following physical keys: Plot, PlotSetup, Num, NumSetup, Symb, SymbSetup, View, or Info. Additionally, the app can also be "run" by using the Apps key, selecting the app, and choosing "Start" from the touchscreen menu. However, each of these buttons do (possibly) different things depending on the code definition for Plot(), PlotSetup(), etc. So unless those functions directly and immediately call HeatIndex(), then of course nothing will run.

Also, when you wrote "Inside App: EXPORT HeatIndex" -- was this to mean that you added EXPORT in front of HeatIndex inside the source code file?
