Dear All,
I am on a very steep learning curve here. I am experienced in C and .NET (the VB kind), however have now ventured into the world of micro-controllers and over the last few weeks have had to learn:
- Linux/Python
- Arduino IDE/CSharp (+ Libraries)
- ESP8266
- MQTT
- NodeRed
And now JSCRIPT! 
I have managed to overcome most hurdles (thank you communities/google/YouTube/etc) but am really struggling with this bit.
Please see the flow I am struggling with below (and attached flow).
I have managed to get the selection list populating correctly in [F:Produce list of Colours], and it is this I am trying to do a better way. I want to setup a Global (or could be Flow) scope JSON array, which is what I have been attempting to do in the two Config nodes:
The end game being to actually define these values within a config file that will be read at startup. However that is another thing to learn about another day. Now I just want to be able to:
- Initialize the Global/Flow JSON array
- Access it from the [F:Produce Global List of Colours] function to produce a msg={"options":colourOptions} message for feeding the Dashboard List box.
Once I can do this, I will then be able to start randomizing the selected list item and sending this out to MQTT.
Very much appreciate any support here, and before anyone says RTFM/Google is your friend, I have and know! 
BR,
Stephen
