Dmx.app.set giving undefined value

Hey @NGM

Firstly, there some info here in formatting code for posts which helps neaten things up for us to read on the forum

How to format code in your posts

Code Formatting When pasting code in your posts, please use the following formatting options, in order to be sure your code is readable and well formatted for the rest of the users.

dmx.app.set('selection', a)

Now remember, this won't update the variable you've created in the UI. It will create a variable that you can use in you app in code though. So you can use it the front end by using {{selection}} anywhere you'd want to use it. Such as dmx-bind:text="{{selection}}"

To be honest, I'd forgotten about using .setValue. not sure if it works all the time and you can just fix the syntax, but dmx.app.set' or 'dmx.global.set will definitely work for you.
