Varify code again, you'll get the missing point.
connection string property has not been initialized????
check your connection string is assigned to the connection object or not.
i can only say this without reviewing actual code.

Create sign up page to add more Accounts in Database.
erro ExecuteScalar requires an open and available Connection. The connection's current state is closed.
Kindly, check your code again and make sure you wrote the if condition to check connection state, if not then write it...
