The XpressDox ScriptIf function
First, read through the article on Scripts to familiarize yourself with that feature.
Using a condition inside a parameterized script requires the use of ScriptIf rather than If. The matching End for a ScriptIf, is a ScriptIfEnd().
It is worth copying-and-pasting this example into a template and trying it out. Note that in the example, the Required and second Rule commands are generated conditionally using the ScriptIf.
