Why is first and last name not outputting?

Question

I need to access a file and then display the content but for some reason I cannot display the full name. I made the variables fname and lname for the first and last name. For now I just wanted to read the first line correctly. I've gone over a lot of help material but have not understood how to figure it out. A push in the right direction or reading material would be awesome. Also anything that you think I could do better. Below is my code.

You need to set fname and lname in your constructor and your toString method is displaying twice fname instead of fname and lname.

BankAccount::BankAccount(string fname, string lname, int accountID, int accountNumber, double accountBalance) {
    this->fname = fname;
    this->lname = lname;
    this->accountBalance = accountBalance;
    this->accountID = accountID;
    this->accountNumber = accountNumber;
    this->accountName = accountName;

};

string BankAccount::toString() {

    return "Account Name: " + fname +" "+ lname +"\n" + "Account Number: " + to_string(accountNumber) + "\n" + "Account Balance: " + to_string(accountBalance) + "\n\n";

}
