 Menu creation is all about structure. First there are variables/constants that go into the **LiquidLine** objects. Then the **LiquidLine** objects go into the **LiquidScreen** objects. Then **LiquidScreen** objects go into the **LiquidMenu** object/s. And optionally the **LiquidMenu** objects go into the **LiquidSystem** object.
 This structure can be established on object instantiation or later with functions:

+#### Methods used:
 ```c++
 LiquidLine(byte column, byte row, A &variableA...);
 ```
 **LiquidLine's** contructor. Takes a column, a row and 1 to 4 variable references.
 
+
 ```c++
 LiquidScreen(LiquidLine &liquidLine1...);
 ```
 **LiquidScreen's** constructor. Takes 0 to 4 **LiquidLine** objects.
 
+
 ```c++
 LiquidMenu(LiquidCrystal &liquidCrystal, LiquidScreen &liquidScreen1..., byte startingScreen = 1);
 ```
 **LiquidMenu's** constructor. Takes a reference to the **LiquidCrystal** object, 0 to 4 **LiquidScreen** objects and the number of the screen that will be shown first.

 ```c++
 LiquidSystem(LiquidMenu &liquidMenu1..., byte startingMenu = 1);

 **LiquidSystem's** constructor. Takes 0 to 4 **LiquidMenu** objects and the number of the menu that will be shown first.

 Callback functions are attached to some **LiquidLine** object. Later they can be called on some event (*e.g. button press*), the function is identified by the **line** on which the focus is and by the number that is passed.

-To call an attached function it needs to be focused (selected) using the `LiquidMenu::switch_focus()` function. When the function is selected, it can be called with `LiquidMenu::call_function(byte functionNumber)`.
+To call an attached function it needs to be focused (selected) using the `void LiquidMenu::switch_focus()` function. When the function is selected, it can be called with `bool LiquidMenu::call_function(byte functionNumber)`.
 Similar functions should be attached with the same number to the different lines. For example 'incrementing functions' can be attached with the number 1, then with a button press (*button 'UP' preferably*), the focused line's incrementing function will be called.
