How do you get the widgets to reflect your code?

Development Tools Cloud IoT

So as far as I know, from what I read on the IoT site, if you put your code under the Arduino cloud .update section of the sketch it should reflect. Why can I not get the widgets to reflect anything? I linked the variables to the widgets and still nothing.

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  int humidity;
  int temperature;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.

remove the int before this call . you have defined it already when setting up variables in the editor

Wow, I am laughing hysterically right now. Something so small. Thanks so much!!!
