I can't be sure without a link to the script you're using, but it looks as if you misread the instructions.
If you reafd something like
The script call is: Luna_Message.config(1,1)
then only the bold part (bold added by me) is the script call, the rest of that line does not belong into the script box.
So the command should read
Script: Luna_Message.config(1,1)
and not
Script: Script Call: Luna_Message.config(1,1)
However, that does not fit with the actual error message you're getting - that error message point to either a forgotten "new game" or a general script incompatibility between two scripts you're using.
So I strongly suggest you follow the link "how to use a script" in my signature to check what the true error is - it might be that you have both errors however.
And if you want better help, we need to know what script you're using, preferably by a link to the website where you got it.
