Remote tank level monitor

I am trying to get this device to work.  I was having issues but have been trying to learn it from zero.  Finally figured out how to AT command a SMS message and reply to it and see it.  I have been successful with using an esp8266 to post a random number to thingspeak.com.  Trying to get the info over cell tower to thingspeak is proving behind my abilities at the moment.  Here is the code I am trying to run through:  No credit for this, I found it and was trying it.....

{

gprsSerial.begin(9600); // the GPRS baud rate

Serial.begin(9600); // the GPRS baud rate

dht.begin();



delay(1000);

}

void loop()

{

float h = dht.readHumidity();

float t = dht.readTemperature();

delay(100);



Serial.print("Temperature = ");

Serial.print(t);

Serial.println(" °C");

Serial.print("Humidity = ");
