Hi,

I have searched everywhere and cannot find how to create a global variable that can be used in all of the screens of a storyboard app. Is this possible?

Thanks,

Warren

I think the best way is to declare them on top of main.lua. After that they are accessible/assignable anywhere. Theoretically you can make them anywhere though.

It’s best to avoid them and do what r.delia pointed out though. For some things they are useful though. [import]uid: 65415 topic_id: 33328 reply_id: 132369[/import]

So if I declare a variable in mail.lua called strName and assign the value “Hello” to it then I can use that variable just like that in other pages? I do not need to refer to main.lua to get the value? I only need one public variable so this sounds like the easiest way if that’s how it works.

Thanks,
