how to interupt a input?

hi
i have 1 input depends on another, when push button 1 (input d3) , button 2 (input d2) low, output (d10) turned high, if button 2 goes high, output have go low, sketch output standing high... how can change that?

my comlete (unfinished) code:

code: [select]

const int pot1 = 0;
const int pot2 = 1;
const int brend = 2;
const int bropp = 3;
const int brned = 4;
const int brlas = 5;
const int brlys = 6;
const int ledac = 7;
const int leddc = 13;
const int ledlys = 8;
const int sollas = 9;
const int solopp = 10;
const int solned = 11;
int brstateopp = 0;
int brstatened = 0;
int brstatelas = 0;
int brstateend = 0;

void setup() {
 
   
 
 pinmode(brend, input);
 pinmode(bropp, input);
 pinmode(brned, input);
 pinmode(brlas, input);
 pinmode(brlys, input);
 pinmode(ledac, output);
 pinmode(leddc, output);
 pinmode(ledlys, output);
 pinmode(sollas, output);
 pinmode(solopp, output);
 pinmode(solned, output);


}

void loop (){

 

 // read end switch
 brstateend = digitalread(brend);
 
 //lift
 brstateopp = digitalread(bropp);
 if (brstateopp == high)
 {
   if (brstateend != high)
   {
     digitalwrite(solopp, high);
   }
 }
 else
 {
   digitalwrite(solopp, low);
 }

 //lower
 brstatened = digitalread(brned);
 if (brstatened == high)
 {
       digitalwrite(solned, high);
 }
   else
 {
   digitalwrite(solned, low);
 }

//retract lock
 brstatelas = digitalread(brlas);
 if (brstatelas == high)
 {
       digitalwrite(sollas, high);
 }
   else
 {
   digitalwrite(sollas, low);
 }



}






frustrated   :-?

we can't see brstateend got value, of relationship between d2, d3, , d10 , brup , solup.

can see of code?
