#### Remarks <a href="#remarks" id="remarks"></a>

* It is possible to nest multiple functions as function parameters.\
  **Example**
  * **AND**(**OR**(**NOT**(<mark style="color:blue;">#cell1</mark> > 5); <mark style="color:blue;">#cell2</mark> < 5); ...
* Before a parameter is used for a function, it is completely evaluated.
* The widget assignment operator (=) returns the assigned value.
