Unable to send data to cloud

Hi, I've been trying out the Arduino Cloud and dashboard (first time using these and first time using MKR GSM 1400). I've been unsuccessful in transmitting the sensor readings to the cloud and aim to use the MKR GSM 1400 wirelessly. Do I have to pack the data before transmission? I'm very lost and any guidance is appreciated!!

/*  
  CloudPercentage moisture_Sensor1;
  CloudPercentage moisture_Sensor2;
  float salinity_Sensor;
  CloudTemperatureSensor temperature_Sensor;

  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.
