attempt to index a nil value

[pogh10]

Hello I keep getting the attempt to index a nil value error, but I put a , 0. I am not sure why this is happening. Below is the error and the line giving me the issue.

Line:

         if pl:getChar():getData("Skill_HP", 0) >= 1 then 

Error:

[ERROR] addons/skillsystem/lua/autorun/server/sv_experience.lua:32: attempt to index a nil value

I can't find the getData method on the wiki... Did you make it yourself? And you should be using [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/string/sub]string.sub[/url], because getChar() is deprecated.

The return value from getChar is nil.

It's not the same `getChar`, Lua is case sensitive
