cfg.set(null, name); ?

 

[STRlantian]

I wanted to create a path called the sender's name

 

[STRlantian]

The first parameter in “set” is the path. And you cannot have a null path. Just remove that line. Paths are separated by . which denotes a new section.

So if I delete that and just do
set(name+".cls", cls);
then it will automatically create a path called [playername].cls: [value] ?

Assuming the variable cls is the value you want to be at that key path, yes.
