Solve the following python programming problem given the following code:
def replace(self, oldtext, newtext) : 
    def rep(w) : 
        if (w == oldtext) : 
            return newtext 
else : 
            return w 
return Phrase (w.fieldname, [rep (w) for w in self.words], slop = self.slop, boost = self.boost) 

    
    

    Fix the buggy line: return Phrase (w.fieldname, [rep (w) for w in self.words], slop = self.slop, boost = self.boost)
