i've got this:
when i enter the main menu and then the class menu i get the message before choosing a class.
and when i enter the class menu by a serveraction i don't get the msg.
also i don't get any change on the player. doesn't equip items that are returned and doesn't cahnge player's speed,maxhp,armor and etc.
another problem:
i get this error:
LUA ERROR: attempt to call a nil value
but this is ONLY then i attack.
i've got hit,attack and attack2 hooks but i haven't used any of those yet.
EDIT: it's not only on attack,attack 2 also gives this error

my problem is that when i open up the main menu in my script and then go to the classes menu:
i receive a message that should receive when i choose a class. not when i enter the classes menu. this happens ONLY when i enter the classes menu by the main menu,if it is by a server action it won't give any message before and after selecting the class.
Also Class Doesn't have any change. i mean it's like i choosed 0 everytime i want to choose my class.
so there's no change in maxhp,armor,weapons to spawn and etc.
Other Problem
Now when i open cs2d with my script. it seems everything is OK except for the spawn problem. BUT it's not, when i use mouse1 or mouse2(attack and attack2) i get an error that says:
LUA ERROR: dir: attempt to call a nil value
but i haven't used the attack or arrack2 hook yet !
