CCS: SMALL PROJECT CODE ASSISTANCE! THANK YOU IN ADVANCE FOR ANY HELP!!

Tool/software: Code Composer Studio

Hi all, I'm in need of a little assistance with a coding project I have going on. I have attached what I have so far along with the requirements needed.

As of this moment, only the "countup" function is working through the S2 Button on the launchpad. The connected third switch to P1.4 and P2.1 is not counting backwards through the LEDs as it should.

All help is greatly appreciated!!

#include <msp430.h>

#define OUTPUTMASK (BIT6 + BIT0 + BIT4)

// Global variables to hold current state and # of pushes
char currentState;
char pushes;
char direction;

void init(void)

    WDTCTL = WDTPW + WDTHOLD;                 // Stop watchdog timer
    P1DIR |= OUTPUTMASK;                      // Set P1.0, P1.6, and P1.4 to output direction
    P1REN |= BIT3;                    		  // P1.3 enable internal resistor
    P1OUT |= BIT3 + BIT4;                      // Set bits 3 and 4 of P1
	
	P2DIR &= ~(BIT1);						  // Makes this an input
	P2REN |= BIT1;							  // P2.2 enable internal resistor
	P2OUT &= ~(BIT1);						  // Make internal resistor pulldown
	

    currentState = 0;                         // Initialize global variable
    pushes = 0;                               // Initialize global variable

        local = 1;
