Trouble with displaying analog values

I'm trying to dummy a trim pot as "sensor" so I can check the code for a prototype I'm building. I've hit a snag right off the bat, as I can't get the analog values to display correctly to my lcd. I'm sure I'm just missing something easy, but I'm real brand new to writing code.
The problem - the display repeats the value from the pot over and over. For example, the value 988 would be 988988988988 over all 32 characters. Thanks for the help.

*/

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the number of interface pins
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

// Set analog pin 0 as sensor output
int sensorPin = 0;
int sensorValue = 0;

void setup() {
// set up the LCD's number of rows and columns:
lcd.begin(16, 2);
}

void loop() {
// read value from sensor
sensorValue = analogRead(sensorPin);

// print value to LCD
lcd.print(sensorValue);

delay(100); // wait 100ms between
// each send
}

When you're printing it just prints at the next cursor position.

You need to set the cursor position if you want the result to appear in the same place on the LCD.

Good luck!
