I am working on a trigger that will populate longitude and latitude fields on the account object. I have a start on it, but I am getting an error:

"Error:Apex trigger AccountBeforeUpsert caused an unexpected exception, contact your administrator: AccountBeforeUpsert: System.LimitException: Too many script statements: 200001"

Trigger: 

trigger AccountBeforeUpsert on Account (before insert, before update) {
  system.debug(Logginglevel.ERROR,'AccountBeforeUpsert  geo updates');    

  List<Id> accountsToUpdate = new List<Id>();
  for(Account theAccount: trigger.new)
  {
    boolean needsUpdate = false;
    if(Trigger.isInsert)
    {
      needsUpdate = true;
    }
    else {
    Account beforeUpdate = System.Trigger.oldMap.get(theAccount.Id);
    needsUpdate = (
      (beforeUpdate.BillingStreet != theAccount.BillingStreet) ||
      (beforeUpdate.BillingCity != theAccount.BillingCity) ||
      (beforeUpdate.BillingState != theAccount.BillingState) ||
      (beforeUpdate.BillingCountry != theAccount.BillingCountry)
      );
    }
    if(needsUpdate)
    {
      accountsToUpdate.add(theAccount.Id);
    }
  }
  if(accountsToUpdate.size() >0 )
  {
    Integer cnt = 0;
    Integer i = 0;
    Integer x = accountsToUpdate.size();
    x = (x>100? 100: x);
    while(i < x){
      List<account> smallList = new List<account>();
      for(Integer k = 0; k == x;)
          break;
      }
      GeoUtilities.updateAccounts(accountsToUpdate);
    }
  }

 Any help with this would be greatly appreciated. Credit for much of the code goes to Bryan at https://bryandf11.wordpress.com/2011/08/22/geocoding-in-apex-triggers-callouts-and-future-methods/

Thanks!
