How to enter values for each level according to the image below?

I hope I'll be clear in my question, what I want is as you see below in the image that I selected layer 1 in the listbox and I've entered different values in the table beside, now what I want that when I select layer 2 in the listbox, the table beside will get blank so that I can enter new values for layer 2 and etc.... for all layers knowing that when I have for example 3 layers and I go back to layer 1, I'll have the numbers which I have entered in this layer saved. I hope you can help me because I'm having a difficulty in it below you can see the image to understand better my question
