Still errors

Code:

Error    14    'string' does not contain a definition for 'SubString' and no extension method 'SubString' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)    C:\mw3server\plugins\Class1.cs    204

im sorry im not good with C#

woops, that should be 'Substring' instead of 'SubString'
