There are a couple of things in the Help.html file that have needed fixing for a while now.
Easy: The help file refers to a function "IsNumber" but the actual function name is "IsNumeric"
Harder: A section on how and where nesting of group calls, functions, and variables is and isn't allowed. In particular, the places where the name of a group, variable, or function can be a string generated by nested group calls, variables, and functions, vs where the name has to be a literal string.
It was not obvious to me, until pointed out in a message some years back, that things like [{Param~terrain,%terrain%}] or [Terrain%type%] could be legitimate group calls. I assumed they would always throw errors.
