ESP8266 Nodemcu Slider Coding Issue

Hello all!

I am very new to Cayenne and Arduino coding as a whole and I am currently facing an issue working the slider widget on Cayenne with the ESP8266 Nodemcu 0.9. The issue is that when I move my slider, the values aren’t updating in the code. Beyond this issue, I am have troubles seeing my sensor, HX711, data on the dashboard. Any help is MUCH appreciated as soon as possible. This is for a project due ASAP. Please refer to the code below. Thank you Cayenne Community!

// This example shows how to connect to Cayenne using an ESP8266 and send/receive sample data.

Before trying the cayenne code, can you try the HX711 code alone to see if you are getting data from the sensor.

why are you using this line?
