How to make a counter using three PBs.?

Hello,
I am wondering how to make a counter using three PushButtons. using ARD Uno R3.

I have this code :

#include <TimerOne.h>
#include <Wire.h>
#include <MultiFuncShield.h>

void setup() 
{
  Timer1.initialize();
  MFS.initialize(&Timer1); // initialize multi-function shield library
  MFS.write("Hi");
  delay(2000);
  MFS.write(-273);
  delay(2000);
  MFS.write(3.141, 2); // display to 2 decimal places.
  delay(2000);
}
int counter=0;
byte ended = false;

void loop() 
{
  if (counter < 200)
  {
    MFS.write((int)counter);
    counter++;
  }
  else if (!ended)
  {
    ended = true;
    MFS.write("End");
    MFS.blinkDisplay(DIGIT_ALL, ON);
  }
  delay(50);
}

for this one, when I push the button A1, it will count up to a certain number. i.e in this one I have sit to 200 then show me a string " end" or maybe anything.
now I have to adjust this code to

switch 1 will count up to a certain number and stop at that number.
switch 2 will count down to zero and stop.
switch 3 will be Reset. I have tried many times to do that but scratched!. wasted.

could you please make it using multifuntion shield ...

thanks

Where does it read the input ?

Post what you tried and describe what was wrong with it

You need code to read and debounce each input, the business logic is the simple bit really...
