Could somebody please give us the code to link a beat sensor microphone to a servo motor so that the motor can move to the beat. Thank you!

That's not how this forum works.
It's not a free code writing service.
For the microphone I recommend you start-out with something like [u]this[/u]. It's got the preamp and all of the other required electronics. That particular board doesn't have a gain control, but it's still a "good start".
If you Google "Arduino beat detection", you'll get some hits and you should be able to find some code that you can adapt to your application.
Beat detection is tricky and it won't be perfect. When we dance or tap our feet to the beat we are not simply reacting to the beat... We "get in the groove" and we anticipate the beat, and then we make unconscious adjustments as the song goes-on. You might want to build some of that artificial intelligence into your code. You may also want to build-in some kind of automatic sensitivity control.
I've made a crude beat detector for my lighting effects. But, the computer crashed and I lost the code. And, I use a peak-detector circuit so the "audio" isn't going-into the Arduino. I did program-in some "smarts"... There's a delay so it doesn't re-trigger for something like 200mS, there is something like a filter so it "likes" to trigger 3 or 4 times per second, and there is automatic sensitivity adjustment. But it is crude and imperfect... But that's OK for me... Lights that blink exactly to the beat get pretty boring after a song or two and I like the imperfection.
What's the servo going to do?
I'd suggest you start by blinking the built-in LED to the beat before you work on the servo part.
There is a [u]Servo Library[/u] so controlling a servo is fairly straightforward. But, servos are slow so it will probably lag the beat. Depending on what you're doing you may need enough "smarts" in your code to anticipate the next beat. Anything mechanical will have inertia and if you don't anticipate the beat the movement will only start after the beat is detected.
