Solve the following python programming problem given the following code:
def collect(self) : 
    def get_or_add(key, new = 0, d = self.hourly) : 
        value = d.get (key) 
        if (value is None) : 
            value = TimeSeries (60, new) 
            d [key] = value 
return value 
for (k, v) in stats.get_gauge_stats ().items () : 
        get_or_add (('gauge:%s' % k)).add (v) 
for (k, v) in self.stats.get_counter_stats (reset = True).items () : 
        get_or_add (('counter:%s' % k)).add (self) 
for (k, v) in self.stats.get_timing_stats (reset = True).items () : 
        get_or_add (('timing:%s' % k), None, d = self.hourly_timings).add (v) 
self.last_collection = time.time () 

    
    

    Fix the buggy line: get_or_add (('counter:%s' % k)).add (self)

#Here is Python code to fix the buggy line: get_or_add (('counter:%s' % k)).

get_or_add (('counter:%s' % k)).add (v)
