Script not running on server

[mia389 10]

This script I found for a target range works on a dedicated server but it acts funny. Multiple targets pop up instead of 1 at a time. When hosted on my machine it works fine. Could someone put the right stuff in this to make it work on dedicated server for me? I tried but don't have enough knowledge

_maxtarg  = 5;
_numtargs = 1;
_skill    = 6;

_targets = [pt1,pt1_1, pt1_2, pt1_3, pt1_4, pt1_5, pt1_6, pt1_7];// target names 
_many    =  count _targets; // count the number of possible targets

_inc     = 0;// keeps track of the number of popup targets triggered 
_score   = 0;// keep count of the targets hit


{_x  animate["terc",1]} forEach _targets;//puts the targets down before the start

_rnumber1=0; 
_rnumber2=0;
_rnumber3=0;

_flag1=0;
_flag2=0;

nopop=true; // sets them to stay down until triggered to popup

player groupChat "Setting Up Range";
sleep 2;
player groupChat "Ready";
sleep 2;


while {_inc<_maxtarg} do 
{
_rnumber1 = random _many;
_int = _rnumber1%1;
_rnumber1 = _rnumber1-_int;


// 1. Check for duplicate targets 
while {(_rnumber1 == _rnumber2) or (_rnumber1 == _rnumber3) or (_rnumber2 == _rnumber3)} do
{  
_rnumber2 = random _many;
_int = _rnumber2%1;
_rnumber2 = _rnumber2-_int;

_rnumber3 = random _many;
_int = _rnumber3%1;
_rnumber3 = _rnumber3-_int;
};
// 1. END

// 2. Set the targets that will popup
_rtarget1 = _targets select _rnumber1;
_rtarget2 = _targets select _rnumber2;
_rtarget3 = _targets select _rnumber3;
// 2. END

// 3. Popup target one always active
_rtarget1 animate["terc", 0];
_inc=_inc+1;
// 3. END

// 3a. Check to see if more than one target is required and opopup at random
// 3b. second target
If (_numtargs > 1 ) then
{
if ((random 2 > 1) and (_inc < _maxtarg)) then
{
_rtarget2 animate["terc", 0];
_inc=_inc+1;
_flag1=1;
};
};
//3b. END

//3c. Third target
If (_numtargs > 2 ) then
{
if ((random 2 < 1) and (_inc < _maxtarg)) then
{
_rtarget3 animate["terc", 0];
_inc=_inc+1;
_flag2=1;
};
};
// 3c. END
// 3a. END

// 4. Time allowed for shooting.
sleep _skill; 
// 4. END 

// 5. Check to see if targets have been hit and count the score
if (_rtarget1 animationPhase "terc" > 0.1) then
{
	_score = _score+1;
	    };
if ((_rtarget2 animationPhase "terc" > 0.1) and (_flag1 == 1)) then

{
	_score = _score+1;
	    };
if ((_rtarget3 animationPhase "terc" > 0.1) and (_flag2 == 1)) then
{
	_score = _score+1;
	    };
// 4. END		    

// 5. Display Score		    
player groupChat format ["Targets :%1 Hit :%2",_inc,_score];
// 5. END

// 6. Reset targets down and restet flags
_rtarget1 animate["terc", 1];
_rtarget2 animate["terc", 1];
_rtarget3 animate["terc", 1];
_flag1=0;
_flag2=0;
// 6. END

sleep 2;
};
sleep 8;
player groupChat "Session Complete" ;

I tried to wrap the whole code with this

if (isServer) then {
...
};

Did not work though
