Which problem do you get, please use [ pawn ] tag too.

But...
Replace

pawn Код:

if ( !strcmp( params, "LoadFs", true ) ) // Idk, this should works though.
if ( sscanf( params, "s", fs ) )

With

pawn Код:

if ( !strcmp( params, "LoadFs", true, 6 ) )
if ( sscanf( params, "s[ 64 ]", fs ) )

Please, add more information, what is the error.
