PRICE_HIGH returning the Value of 2

Hi

 I am trying to write a simple script to alert me if a pair is close to a resistance or support price. However when I try to use PRICE_HIGH instead of giving me the highest price for that pair in the given time frame, it just gives the value 2.

 See the program I have attempted.

 Any help will be gratefully recieved.

int Count=0;                                    // Global variable

int start()                                     // Special funct. start()

   {

   double PRICE_HIGH;

   double Price = PRICE_HIGH;                           // Local variable

   Count++;

   Alert("New tick ",Count,"   Price = ",Price);// Alert

   return;                                      // exit start()

   }

int init()                                      // Special funct. init()

   {

   Alert ("Function init() triggered at start");// Alert

   return;                                      // Exit init()

   }

int deinit()                                    // Special funct. deinit()

   Alert ("Function deinit() triggered at exit");// Alert

   return;                                      // Exit deinit()
