Whenever you see the plus and expand icons in the Web interface after a text box or

the icon with three dots in the Designer

 it means that M&D is expecting an expression in this text box.

Examples of valid expressions:

"This is a text"

"Sales report - " & Date.Today.ToString("dd.MM.yyyy")


[Datasource].[Executive Dashboard].[Expression].[sum(Sales)]

"Sum of sales: "  & [Datasource].[Executive Dashboard].[Expression].[sum(Sales)]
