Rovie, I need help with my code. Maybe someone there can help me sort it out. I am trying t add a SD card, But cant seem to get the construct of the variables correct. (at the end of the code its all // remed out) Thanks

// VIPER 37 Altimeter, Accelerometer, temp, Blue LCD,
// Mega 2560 V3
// LCD = I2C
// Temp = pin 2
// Accel = X=A0, Y=A1, Z=A3. Always awake, Always 5v, Always Low
// Altimeter = MS5607, RevA, Parallax, I2C
#include <Wire.h> //Alimeter ?
#include "IntersemaBaro.h" //Altimeter

// On the Ethernet Shield, CS is pin 4. Note that even if it's not
// used as the CS pin, the hardware CS pin (10 on most Arduino boards,
