hi ,, i have this essue with my program
" error: expected constructor, destructor, or type conversion before '.' token"
recieving this error each time ! anyone help 
i really need help i don't have much time to finish the program.. please correct this for me .. thanx

Please read Read this before posting a programming question ... - Programming Questions - Arduino Forum
specifically #6, and please use ^T to format the code to be readable.
The message is indicating that you problem called a function before it was ready. I'm guessing (since I've had a similar problem) that you did not call the constructor or that you called it before everything was ready.
Is this maybe a problem?
SoftwareSerial bluetooth(10, 11); // RX, TX
i noticed that you are not using it anywhere.
ALL code belongs in a function. Starting with
 int x,y,z; //triple axis data
 Wire.beginTransmission(address);
 Wire.write(0x03); //select register 3, X MSB register
 Wire.endTransmission();
your code is NOT in a function.
