StormTronics CMS Error

[Zendah]

Here's the problem: everything works fine until I select Options.  Then it shows this error:

Script 'Blizzard's CMS' line 1043: TypeError occured.
no implicit conversion from nil to integer

and the game crashes.  I have the script right above Main and it's the only custom script I'm using right now.
This is line 1043:
    @font_name = BlizzCFG::CMS_FONTS[@current_font]
I'm using RMXP, in case anyone needs to know.

Please help if you can!

EDIT: Actually it's line 1042.  Sorry about that!  (I have the right code there, though)

Actually I've had this problem as well. Its because you don't have the current font you're using in the selectable options as well. And what Blizz said. Lol

Because once I put in the font that I was using as a selectable one then it disappeared.
