IF actions test the presence or absence of an attribute unless the object is a Boolean/bool, in which case it tests the attribute for true/false. The only operator allowed is "not" and means either "not present" or "not true". For example, "$if(!member)$...$endif$".
You can also use elseif to make a chain of tests:
| No Format |
|---|
$if(x)$
...
$elseif(y)$
...
$elseif(z)$
...
$else$
...
$endif$

The first true expression "wins".
