Variable storing on Arduino uno

hello,


i want echosendrecievenorth/east/west read time takes till gets back, convert centimeters , store ncm/ecm/wcm. want read these values , make decision based on these values. after decision has been made want execute things, , rescan area. how store these value's? here code:

code: [select]

#include <servo.h>

int snorlinks = 5;
int snorrechtsstaat = low;
int snorlinksstaat = low;
int ontvanger = 7;

long eduration, ecm;
long nduration, ncm;
long wduration, wcm;
int led = 13;

servo left;
servo right;
servo top;
void setup() {
  serial.begin(9600);
  top.attach(9);
  left.attach(11);

  pinmode(snorrechts, input);
  pinmode(snorlinks, input);
  pinmode(echo, output);

      }

thanks help

you've got awful lot of code there doesn't know how assign simple variable.

what i'm trying if you're stuck, lot of @ few basic c++ tutorials , maybe few of example sketches come ide. 

what you're asking right analogous to...  "i gonna drive truck, steering wheel?" 

if want copy , paste way through writing code that's fine, don't expect able modify of in meaningful way.
