quick multi condition question

i'm artist, not programmer. i'm trying basic in code possible.

playing around pinball code. want 3 switches light 3 separate leds. when 3 leds lit, want lights go out, , ready turned on again next time hit them.

right each of lights light when hit switch assigned them. when 3 lit, not turn off again.  doing wrong?

code: [select]

// 3 target scrore function. when target hit lights , provides points.
// when 3 targets lit flash , provide jackpot
// when jackpot provided lights turn off.
 


int led_d1 = 11;
int led_d2 = 12;
int led_d3 = 13;
int switch_d1 = 1;
int switch_d2 = 2;
int switch_d3 = 3;


void setup() {
  // put setup code here, run once:



pinmode(led_d1,output);
pinmode(led_d2,output);
pinmode(led_d3,output);
pinmode(switch_d1,input);
pinmode(switch_d2,input);
pinmode(switch_d3,input);


}

void loop() {
  // put main code here, run repeatedly:

//drop target switch 1 

     if (digitalread(switch_d1) == low)
        {
         digitalwrite(led_d1,high);
        }
 
//drop target switch 2

     if (digitalread(switch_d2) == low)
        {
         digitalwrite(led_d2,high);
        }

//drop target switch 3 

     if (digitalread(switch_d3) == low)
        {
         digitalwrite(led_d3,high);
        }

//if 3 lit up, award bonus , reset lights low//


     if (led_d1 == high && led_d2 == high && led_d3 == high)
        {
         (led_d1 && led_d2 && led_d3 == low);
        }

}

this

code: [select]

       {
         (led_d1 && led_d2 && led_d3 == low);
        }

is cracked

you might mean

code: [select]

       {
         digitalwrite(led_d1, low);
          digitalwrite(led_d2, low);
         digitalwrite(led_d3, low);
        }
