Have you noticed that you are assigning the car colors into the player's enum?

pawn Код:

Player[playerid][CarCol1] = col1;
Player[playerid][CarCol2] = col2;

Also, change the if statement into this:

pawn Код:

if( (col1 >= 0 && col1 < 300) && (col2 >= 0 && col2 < 300) )

Because, the current one will only check if one of the colors is correct, but not both of them. So you can enter one valid color and another invalid.
