So my last post got shut down for being too broad, so I've fixed some things and narrowed this down. Now when I try to run this, I get errors on line 136 which is the PrintAccount override in the CheckingAccount class and on line 148 which is the Main class in AccountTest. The error that pops up says: "An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll Additional information: Input string was not in a correct format." and I have no idea how to fix it. Any guidance would be appreciated. Thanks.

You have a \t{1) instead of a \t{1}
public override void PrintAccount()
{
Console.WriteLine("Account Name :\t{0}\nAccount Number :\t{1)\nBalance :\t{2:C}\nFee Charged :\t{3:C}", accountName, accountNumber, balance, feeCharged);
}
should be
public override void PrintAccount()
{
Console.WriteLine("Account Name :\t{0}\nAccount Number :\t{1}\nBalance :\t{2:C}\nFee Charged :\t{3:C}", accountName, accountNumber, balance, feeCharged);
}
