when i want to launch a map this appears:

unlocalized (mymap_intro1)
unlocalized (mymap_intro2)
unlocalized (mymap_intro3)
unlocalized (mymap_intro4)

why is this text appearing instead of mine?

....and in the list of the tasks my text also doesnt appear.

You need to put your strings in a .STR file (?:\Call of Duty 4 - Modern Warfare\raw\english\localizedstrings).
Then in script preCache them and use them however you want.

precachestring( &"MYMAP_INTRO1" );

Objective_Add( 0, "active", &"MYMAP_INTRO1" );

there is trouble always yet

my script:

main()
{

level.weaponClipModels = [];
level.weaponClipModels[0] = "weapon_m16_clip";
level.weaponClipModels[1] = "weapon_dragunov_clip";
level.weaponClipModels[2] = "weapon_ak47_clip";
level.weaponClipModels[3] = "weapon_g36_clip";
level.weaponClipModels[4] = "weapon_ak74u_clip";
level.weaponClipModels[5] = "weapon_mp5_clip";
level.weaponClipModels[6] = "weapon_saw_clip";


maps\_load::main();
maps\_nightvision::main(); 


level.player takeallweapons();
level.player giveWeapon ("saw");
level.player giveWeapon ("m4_grenadier");
level.player givemaxammo( "m4_grenadier" );
level.player giveWeapon ("fraggrenade");
level.player giveWeapon ("flash_grenade");
level.player switchToWeapon( "m4_grenadier" );

precacheString( &"MYMAP_INTRO1" );
precacheString( &"MYMAP_INTRO2" );
precacheString( &"MYMAP_INTRO3" );
precacheString( &"MYMAP_INTRO4" );
precacheString( &"MYMAP_OBJ_1" );
precacheString( &"MYMAP_OBJ_2" );
precacheString( &"MYMAP_OBJ_3" );

Objective_Add( 0, "active", &"MYMAP_INTRO1" ); 
Objective_Add( 0, "active", &"MYMAP_INTRO2" ); 
Objective_Add( 0, "active", &"MYMAP_INTRO3" );

What version of COD4 are you on? I know that older versions have weird problems with locstrs.

1.7 patch

please help me

is your strings file called mymap.str?

yeah

Here's an example that I'm using atm.

main()
{
PreCacheString(&"MYLEVEL_OBJECTIVE_POWER");
level thread objective_00();
}

objective_00()
{
who = undefined;

master_switch = getent("use_master_switch","targetname");
origin_one = getent("master_switch", "targetname");
rotatedoor = getent("rotatedoor", "targetname");

Objective_Add( 0, "active", "MYLEVEL_OBJECTIVE_POWER" );
Objective_Position( 0, origin_one.origin );
Objective_State( 0, "active" );
objective_current(0);

master_switch waittill( "trigger", who );
Objective_State( 0, "done" );
Objective_Delete( 0 );

rotatedoor RotateYaw( 100, 2 );

level thread objective_01();
}
