problem with config.cpp

I´m trying to add some new sounds to the AH-6 gatlin guns and wrote this config (shown with the old sounds):

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

class CfgPatches

{

class SDP_Twin

       {

units[] = { "SDP_AH6" };

weapons[] = { "SDP_TwinM134" };

requiredAddons[] = {"CAData", "CA_Anims_Char", "CACharacters", "CAWeapons", "CASounds", "CATracked", "CAWheeled", "CAAir"};

requiredVersion = 0.102000;

};

};

class CfgVehicleClasses

{

class SDP_Vehicles

       {

displayName = "SDP";

};

};

class Mode_SemiAuto {};

class Mode_Burst : Mode_SemiAuto {};

class Mode_FullAuto : Mode_SemiAuto {};

class cfgWeapons

{

/*extern*/ class TwinM134;

class SDP_TwinM134: TwinM134 {

modes = {"LowROF","HighROF"};

canLock = 0;

class LowROF: Mode_FullAuto {

sound = {"\ca\Weapons\Data\Sound\m134loop4_end", 10.000000, 1};

};

class HighROF: LowROF {

sound = {"\ca\Weapons\Data\Sound\m134loop3_end", 10.000000, 1};

};

};

};

class CfgVehicles

{

/*extern*/ class AH6;

class SDP_AH6: AH6 {

vehicleClass = "SDP_Vehicles";

weapons[] = {"SDP_TwinM134"};

};

};

If i choose this unit in the editor, an error message hint:

Quote[/b] ]Size: `modes/´ not an array

Somebody has an idea?!

Kind regards

S.D.

Maybe

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">modes = {...

should be

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">modes[] = {...

like in original config?

Now i´m totaly confused. In the original config its also

Quote[/b] ]modes = {....

but it seems to work with

Quote[/b] ]modes[] = {....

thanks
