> Subject: Evaluate Section
> To: [email protected]
> Hello,In the Evaluate section, there are two different variables: $source1
> and $source. How can it display "abc" when $source is never defined?
> Evaluate
> The *#evaluate* directive can be used to dynamically evaluate VTL. This
> allows the template to evaluate a string that is created at render time.
> Such a string might be used to internationalize the template or to include
> parts of a template from a database.
> The example below will display abc.
> #set($source1 = "abc")
> #set($select = "1")
> #set($dynamicsource = "$source$select")
> #evaluate($dynamicsource)

> That's a good point though. Perhaps the example should use concatenation to
> be clearer. The single quotes prevent evaluation.
> #set($dynamicsource = '$source' + "$select")
