I freely admit I'm a complete gimbo when it comes to scripting...
 

Okay, project goal: Incorporating Elements originating from Forgotten Realms CS (specifically the ideas of Regions/Homelands) for a custom campaign setting.

However, I have a plan for different races to have different options even within the same homeland/region, I'm wondering how to script a requirement for Home: Sorintha - Human to restrict it to just humans?

I'm a good planner. Horrible engineer, so any help is greatly appreciated!

In the Expr-Reqs section of that template, add the following message:

And the Expression:

awesome, thanks. I'm really sorry for not being able to figure out something really basic.
