Class LeadProcessor must implement the method: void Database.Batchable<SObject>.execute(Database.BatchableContext, List<SObject>)

Hi,

I keep getting the following compile error:

Class LeadProcessor must implement the method: void Database.Batchable<SObject>.execute(Database.BatchableContext, List<SObject>)

FYI, here is my class code:

global class LeadProcessor implements Database.Batchable<Sobject>
    {    

    global Database.QueryLocator start(Database.BatchableContext bc) 
    {
        return Database.getQueryLocator([SELECT LeadSource FROM Lead]);
    }

    global void execute(Database.BatchableContext bc, List<Leads> scope){
        // process each batch of records
        for (Leads l: scope) {
             l.LeadSource = 'Dreamforce';
             recordsProcessed = recordsProcessed + 1;
            }
        update scope;
    }    

    global void finish(Database.BatchableContext bc){}    
}

Please assist. Thanks

Varible recordsProcessed  is not defined,

Please update your code like below 
global class LeadProcessor implements    Database.Batchable<Sobject> 
{
    global Database.QueryLocator start(Database.BatchableContext bc) 
    {
        return Database.getQueryLocator([Select LeadSource From Lead ]);
    }

    global void execute(Database.BatchableContext bc, List<Lead> scope)
    {
            for (Lead Leads : scope) 
            {
                Leads.LeadSource = 'Dreamforce';
            }
        update scope;
    }    

    global void finish(Database.BatchableContext bc){   }
