Hash Table help

[Samariyu]

Hey, guys. I'm working on making a simple Hash table, and I'm using vectors. The problem I'm having is whenever I try and search through a list, like below.

(this is the funtion that will insert an item into the table)

The seg fault happens at the if statement, and I'm getting this same error every time I use that if statement. the bucket is correct, and the capacity should be 30. Any ideas? Do you need to see more code?

 void HashTable::insert(string name){
	long bucket = hashFunction(name);
	for(int i = 0; i < this->size; i++){
		if(list[bucket].at(i).find(name)!= string::npos)
		{
			cout<<"name was found, cannot insert"<<endl;
			cout<<"bucket: "<<bucket<<" name: "<<name<<endl;
			
		}else{
			cout<<"name was not found"<<endl;
	
			list[bucket].at(i) = name;
			this->numEntries++;
		}
	}
}

It would help to see what hashtable.h and hashfunction() looks like.

My first guess is that the value returned by hashFunction exceeds the number of entries in list.
