Incubator turning eggs

hi first arduino project.

my project move dc motor running shuttle along bed turn eggs (parts old flat bed scanner) , l293 runs motor

egg holder, box, rocker made.

the following code "should" upon button press or timer move shuttle 1 end other , stop. wait button or timer move other end. each end has push button read shuttle @ end of travel.

if on code not working

code: [select]



// egg rotation v5
// control small dc motor driven carriage shuttle left right, limit switch @ each end stop travel.
// if switch or timer (not setup yet) triggered, run other end , stop.
int left = 5; //motor on pin 6
int right = 6; // motor on pin 4
int enable = 3; // "h bridge" pwm speed pin 1 on ic
int limitswitchleft = 7; //travel @ full left position on pin 7
int limitswitchright = 8; //travel @ full right position on pin 8
int whereisshuttlenow = 1; //name var current position
int wherewasshuttlelast = 1;// name var ws last
int motorspeed = 200; //set pwm motor speed
int sendcarrage = 2; // switch on pin 2

void setup()
{
pinmode(left, output); //name pin number x output
pinmode(right, output); //name pin number x output
pinmode(enable, output); //name pin number x output
pinmode (limitswitchleft, input); //set switches input
pinmode (limitswitchright, input); // set switches input
pinmode (sendcarrage, input); // set input
//digitalwrite(enable, high); //stop motor travel


 wherewasshuttlelast = 1; //set random start position
}
void loop()
{
     if (digitalread (sendcarrage) == high) { //see if carrage button pressed or timer code trigger
       if (wherewasshuttlelast == -1) {//if shuttle flag last left (-1)
       delay (2); //wait clear swtich
       runright();
      
        if (digitalread (limitswitchright) == high) { //if carrage full travel right
        wherewasshuttlelast = 1;
        motorstop();
         }

else {
if (wherewasshuttlelast == 1) {//if shuttle flag last right (1)
        //if (whereisshuttlenow == 1)
        delay (2); //wait clear swtich
        runleft();
         //move outside sendcarrage command
        if (digitalread (limitswitchleft) == high) { //if carriage full travel left
        wherewasshuttlelast = -1;
        motorstop();
    
   }}}}}
 }
 
////////////////////// end main loop
 //setup subs
  void runleft(){ // run motor left
  digitalwrite(enable, high); //  turn on ic chip
  analogwrite (right, motorspeed);
  digitalwrite (left, low);
  }
  void runright (){ //run motor right
  digitalwrite(enable, high); // turn on ic chip
  digitalwrite (right, low);
  analogwrite (left, motorspeed);
  }
  
    void motorstop(){ //stop motor
  digitalwrite(enable, low); //  turn on ic chip
  digitalwrite (right, low);
  digitalwrite (left, low);
  }

if on code not working

you have switches wired in mysterious way. have code something. have failed include relevant details. , want guess why code doesn't want? i'll pass.
