I am not a developer but long time SharePoint power user and admin.  I'm exploring the Pro version of Rich Forms but am having a difficult time understanding the expression coding in some instances.  Canyou point me to any resources for learning more about the underlying code/logic and definitions?

 

For example, I'm trying to add in a visibility rule to a tab based on a field being populated vs blank.  I have the logic as:  ?[[_field_name]] != " "

 

Do I need a value in the quotes to denote "blank" or "null?"
