Description: $$Variables - repeating - don't display as merge fields
How to replicate: see attachment
Workaround: none that makes sense
If you set $$Var = "Hello" in a script, having it on a layout as merge var <<$$Var>> does not compute - nothing is displayed.
OTOH, a repeating variable IS evaluated and displayed, for example <<test::var>>.
