The Expression Editor

Introduction

The expression editor is a simple tool which will allow you to produce complex expressions and/or functions that contain the correct syntax. To open the editor, click on the button to the right of the expression field.

Selecting either of the options above the line will define the information in the field. A "String Literal" or "Numeric Literal" will define the information in the field as being a string or a number. Selecting the expression option will define the information in the field as being an expression.

If you recall earlier in the series, I mention that quote marks will be your nemesis. It's here where you decide what has quote marks (a string) and what doesn't (an expression).
