Retrieve value from slider

@Erin_Thompson
Hi,
In using the Particle trigger I am able to send 3 values to the dashboard indicator.
With the goal to get added the slider value to the workflow payload I assembled
the attached workflow. I’m using a Device:update node to retrieve the slider0 value and add it to the workflow payload. I’m not having success on that.
I do not see what exactly I am doing wrong , I am trying to follow the Brandon suggestions at:

Can you give me some tip on how I should config the device : update node ?

Thank you in advance.:slightly_smiling_face:
