Post Help with my program please.
This is turning into the longest program I've written by myself, as a beginner programmer I'm having some difficulties with the syntax and compiling the program. If anyone could suggest ways to fix my program please let me know. Below is the program I have right now.

Code:
#pragma config(I2C_Usage, I2C1, i2cSensors)
#pragma config(Sensor, dgtl1,  limitswitch,    sensorTouch)
#pragma config(Sensor, dgtl2,  sonarSensor,    sensorSONAR_cm)
#pragma config(Sensor, I2C_1,  rightEncoder,   sensorQuadEncoderOnI2CPort,    , AutoAssign)
#pragma config(Sensor, I2C_2,  leftEncoder,    sensorQuadEncoderOnI2CPort,    , AutoAssign)
#pragma config(Motor,  port2,           rightMotor,    tmotorVex393, openLoop)
#pragma config(Motor,  port3,           leftMotor,     tmotorVex393, openLoop, reversed)
#pragma config(Motor,  port8,           armMotor,      tmotorVex393, openLoop)
#pragma config(Motor,  port9,           clawMotor,     tmotorVex393, openLoop)
//*!!Code automatically generated by 'ROBOTC' configuration wizard               !!*//

void moveStraight()
{
  if(SensorValue[leftEncoder] > SensorValue[rightEncoder]
  {
    motor[rightMotor] = 63;
    motor[leftMotor] = 50;
  }
  if(SensorValue[rightEncoder] > SensorValue[leftEncoder])
  {
    motor[rightMotor] = 50;
    motor[leftMotor] = 63;
 
  if(SensorValue[leftEncoder] == SensorValue[rightEncoder])
  {
    motor[rightMotor] = 63;
    motor[leftMotor] = 63:
  }


void grab()
{
  if (limitswitch == 1)
  {
    motor[clawMotor] = 27;
    wait1Msec(500);
  }
     while(SensorValue(sonarSensor) > 20  || SensorValue(sonarSensor) == -1)
      motor[rightMotor] = 63;
      motor[leftMotor]  = 63;
   }


void drop()
{
  motor[armMotor] = 127;
  wait1Msec(5000);
     while(SensorValue(sonarSensor) > 10  || SensorValue(sonarSensor) == -1)
  {
    motor[rightMotor] = 63;
      motor[leftMotor]  = 63;
   }
   motor[clawMotor] = -127;
   wait1Msec(500)
}

task main()
{

SensorValue[rightEncoder] = 0;
SensorValue[leftEncoder] = 0;

  while( limitswitch == 0 )
  {
    moveStraight();
  }
 
else
  clawMotor = 127;
}


Here are error messages I'm receiving.

File "RobotMaze6-5-12.c" compiled on Jun 10 2012 16:43:38
15: *Warning*:expecting '[' and found '{'. Typing error assumed and '[' used.

Thanks again to anyone who is willing to help!

Post Re: Help with my program please.
Just a quick note;

you should select all your code (ctrl-a)
then apply formatting to it (ctrl-alt-F)

this will help you see where your braces might not line up. When I did this with your code,
I immediately noticed that the first function, moveStraight, probably did not close as you expected it to.

That will help get you started.

//Copy and paste this into your robotc interface. I don't have the vex system, so I could'nt
//help with that, but it fixes all the other errors. Mainly, you just left out end braces.
//Also, try to keep your code aligned by using the tab key or smart indexing.
//Other than that, you understand the basics of the language very well.
