Android app widget. Can't get mqtt.publish service to work

EDIT: It looks like the comma is the offending item but you don’t have to stick to what is presented in the select list.


I can’t get a widget to work using mqtt.publish
What am I doing wrong?

I am using Mqtt Explorer to monitor messages but nothing comes through.
I don’t know if the comma in the Qos field is a problem but the it puts it there automatically.

Thanks.
