How to make a toy car moves forward using the Pololu VNH5019?

Hello, we are making a two-wheeled toy car controlled by Arduino and Pololu VNH5019. The sample program provided by Pololu drives only one motor at a time. How to make the program to drive the car forward? Can anybody please provide a sample code?

The following code does not work:

void loop()
{
:
:

md.setM1Speed(100);
md.setM2Speed(100);

:
:
}

Thanks

For informed help, define "does not work" and post all the code, using code tags.

I don't have the computer with me now. By doesn't work, I mean only one motor could turn at a time. In other words, we couldn't get the car to move forward. Can anybody share a sample program?

Thanks but this program only drives one motor at a time. I am looking for a sample program that drivers two motors at the same time to move the car forwards.

Just post your code when you are at the right computer, it will become obvious then.
