The Expression Box

The Expression-Box is where you build your Expression. As you type, the tool provides a list of suggestions at each word of the Expression.

Also, at each word, the tool provides a Toolbar with buttons applicable to the current word. See Constructing Expressions for more details.


Before saving an Expression, you should provide an alias for the Expression. The Alias will be used when inserting the Expression into the Question-box as shown below:
