Skin vs Core temp and Heat Zones

[Sebastian240682]

Hi.
I am using the Core Body Sensor with a Wahoo Bolt Elmnt V2.
Unfortunately the diagram “Skin vs Core temp and Heat Zones” is not working and the following error message is displayed:
ReferenceError: “skintemp” is not defined
I am really struggling how I can solve the problem, also a customized approach was not working.
Thanks in advance

Is the SkinTemp field already set up / added?

also, I don’t see this “custom chart” in the custom chart list.
