combining two functions in GUI

hey everyone

i am doing a project using the GUI and i am trying to use the the unit step and ramp functions with a fuction, how should i combine the two functions (user input function and the unit or ramp fuction) in one function when using the scaling property for both of them?

Your callback function should collect the user inputs and call the other functions, just like you would in a script. So if you want to create a GUI, make sure you have a working script first.
