Customer Account banking system error with variable input
Im building a banking system. in my create_account it asks for account address and phone number as well as other questions. When I go to my Show account info (balance inquiry) I notice its not getting the right address as well as phone number. its showing "garbage". Im not sure whats going on If you can point me in the right direction and help out that would be appreciated.
