Using this code, when a successful login is created and you click okay when it says you have successfully logged in, I want it to go to another screen with a vertical list of the options and a data entry space next to type in them. These are as followed; Enter temperature in degress (then a place for the user to type) next line would be Enter wind speed in mph, Then dew point, wind chill andfinally cloud base. Add another class to the project and have main call this screen or window. Thanks!
