You need to wrap them inbetween { }

pawn Код:

new cInfo[][ClassInfo] =
{
    {"Assault", "The most basic class of all the classes.", 0, {34, 34, 34}, {100, 100, 100}},
    {"Assault", "The most basic class of all the classes.", 0, {34, 35, 36}, {100, 100, 100}},
    {"Assault", "The most basic class of all the classes.", 0, {37, 38, 39}, {100, 100, 100}}
};

and you also forgot the , on the first two.
