Hi. I'm new at C and am doing a project for a class. My project partner just learned to use sub routines but we're having trouble. Could someone suggest what might be wrong?

 int a, b, c, x, portaval;					// Declare variables for loop

main()
{
	PORTA = 0;
	PORTC = 0;
	CMCON0 = 7;					// Turn off comparators
	ANSEL = 0;					// Turn off ADC
	TRISA0 = 0;					// Make RA0/RA1/RA2/RA4/RA5/RC0/RC1/RC2/RC3/RC4/RC5 outputs
	TRISA1 = 0;
	TRISA2 = 0;
	TRISA4 = 0;
	TRISA5 = 0;
	TRISC0 = 0;
	TRISC1 = 0;
	TRISC2 = 0;
	TRISC3 = 0;
	TRISC4 = 0;
	TRISC5 =0;
	TRISA3 = 1;					// Make RA3 input 
    a = 0;
    b = 0;
    c = 0;
	x = 0;
	portaval=x;
	
	while (1==1)				// Loop forever
	{
		if (RA3==1)				// button is pressed
		{
			b = b + 1;			// Counter
		} // fi

		if (b==1)				// button is pressed for the first time
		{
			x = showrider();
			blinkled(x);
		}				
		else if (b==3)			// button is pressed for the third time
		{
			x =	showrider();
			blinkled(x);	
		}	
		else if  (b==5)			// button is pressed for the fifth time
		{
			x = showrider();
			blinkled(x);	  
		}
		else if (b==7)			// button is pressed for the seventh time
		{
			x = showrider();
			blinkled(x);		  
		}
		else if (b==9)			// button is pressed for the nineth time
		{
			x = showrider();
			blinkled(x);
		}		  
	} //elihw
} // end main

int showrider()
/* Knight Rider Effect*/
{
	while (RA3==1)				// wait for the user to lift finger after pressing button
	{
	} // elihw

	while (RA3==0)				//while button is not being pressed
	{
		PORTA = 0b000001;
		for (a=0; a= 1 && b
