problem integrating my code with plx daq code

Hello everybody! I'm really new in Arduino. I have a project going on right now about the MPU6050 accelerometer sensor. I was trying to gather the data and plot in PLX-DAQ in real time but for some reason the PLX-DAQ is not showing any values in the table. Also, the values that's coming from the sensor is reading in Display direct debug window but nothing is showing up in the excel spreadsheet. I just want the raw data from coordinate x, y, z displaying and graphing realtime in excel spreadsheet. Below is my program and some screens shots. It would be a very big help if someone can help me with this one. Thank you everybody

here is my code

#include "Wire.h"
const int MPU_ADDR = 0x68;
int16_t accelerometer_x, accelerometer_y, accelerometer_z, accelerometer_amp;

int16_t gyro_x, gyro_y, gyro_z;
int16_t temperature;

char tmp_str[7];
char* convert_int16_to_str(int16_t i)
sprintf(tmp_str, "%6d", i);
return tmp_str;
}
void setup() {

Serial.begin(115200);
Wire.begin();
Wire.beginTransmission(MPU_ADDR);
Wire.write(0x6B);
Wire.write(0);
Wire.endTransmission(true);

}
void loop() {

Wire.beginTransmission(MPU_ADDR);
Wire.write(0x3B);
Wire.endTransmission(false);
Wire.requestFrom(MPU_ADDR, 7*2, true);

// "Wire.read()<<8 | Wire.read();" means two registers are read and stored in the same variable
accelerometer_x = Wire.read()<<8 | Wire.read();
accelerometer_y = Wire.read()<<8 | Wire.read();
accelerometer_z = Wire.read()<<8 | Wire.read();
temperature = Wire.read()<<8 | Wire.read();
gyro_x = Wire.read()<<8 | Wire.read();
gyro_y = Wire.read()<<8 | Wire.read();
gyro_z = Wire.read()<<8 | Wire.read();

// print out data
Serial.print("aX = "); Serial.print(convert_int16_to_str(accelerometer_x));
Serial.print(" | aY = "); Serial.print(convert_int16_to_str(accelerometer_y));
Serial.print(" | aZ = "); Serial.print(convert_int16_to_str(accelerometer_z));

//recordGyroRegisters();
Serial.println( (String) "DATA," + accelerometer_x + "," + accelerometer_y+ "," + accelerometer_z);
delay(100);

delay(300);
}

here is my code

That code hasn't a hope in hell of compiling. So, why did you waste time posting it?
