Arduino Function value to glcd

I am new to Arduino and I’m trying my first pro mini. i was able to find some ds1302 code from github that runs perfectly, my problem is trying to add some lm35 code to also display temperature data as well as the time data.

The code doesn’t seem to run the celsius and fahrenheit functions. i have attached my code any help will be appreciated.

// Setup Serial connection

//Serial.begin(9600);

// The following lines can be commented out to use the values already stored in the DS1302

// Once you flash the arduino with the correct time.

//rtc.setDOW(FRIDAY); // Set Day-of-Week to FRIDAY

//rtc.setTime(12, 0, 0); // Set the time to 12:00:00 (24hr format)
