MT5 Array and error of array out of range.

[ericmslim51968280982]

Hi, I am new to programming MT5 Market Book following the " MQL5 Cookbook Implementing your Own Depth of Market" instructionn"

After compiled ok for Expert.mq5, MarketBook.mqh and MarketBook.mq5, and when I debug, it gives error message as 

MQL5 DEBUGGER: Critical error while running expert Expert (GBPUSD,H1).  Array out of rangge. at line 363 

Is anybody can help, what is this error means for?  How to solve it.  It seems that the error means the array info return by MarketBookim_best_ask_index).price; is out of range.  Any one has come across this error out of range.  Please help.  Thank.
