link set only chaing root prim

I cannot get this script to change the whole linkset, it only changes the root prim.

What am i doing wrong?

default//Daytime
{
    state_entry()
    {
        llSetTimerEvent(200);
        vector sun = llGetSunDirection(); 
        if (sun.z < 0) state night;//This says, it's night time
        else//This is for if it's daytime
        {
            llSetAlpha(0.0, LINK_SET);
            llSetLinkPrimitiveParams(LINK_SET, [PRIM_GLOW,ALL_SIDES,0.0]);//Turn glow off
        }
    }
    timer() 
    {
        llResetScript();//Reset the script to see if it's still daytime  
    }    
}
//Everything uptop is the same as down here accept it's the opposite.
state night
{ 
    state_entry()
    {
        llSetTimerEvent(200);
        vector sun = llGetSunDirection(); 
        if (sun.z > 0) state default;
        else
        {
            llSetAlpha(1.00, LINK_SET);
            llSetLinkPrimitiveParams(LINK_SET, [PRIM_GLOW,ALL_SIDES,0.15]);
        }
    }
    timer() 
    {
        llResetScript();  
    }    
}

llSetLinkAlpha perhaps?

you're setting the ALL_SIDES and LINK_SET are the same value, but you are actually using the wrong one in your calls above... the link version takes 3 parameters, and the link target is the first, not the last (side(s) is last for both)

FFS now it won't compile and i have 2 start again

this script took me 4 weeks to make and now its ballsed

keeps saying Function call mismatches type or number of arguments.

default//Daytime
{
    state_entry()
    {
        llSetTimerEvent(200);
        vector sun = llGetSunDirection(); 
        if (sun.z < 0) state night;//This says, it's night time
        else//This is for if it's daytime
        {
            llSetLinkAlpha([LINK_SET, 0.00]);
            llSetLinkPrimitiveParams(LINK_SET, [PRIM_GLOW, 0.0]);//Turn glow off
        }
    }
    timer() 
    {
        llResetScript();//Reset the script to see if it's still daytime  
    }    
}
//Everything uptop is the same as down here accept it's the opposite.
state night
{ 
    state_entry()
    {
        llSetTimerEvent(200);
        vector sun = llGetSunDirection(); 
        if (sun.z > 0) state default;
        else
        {
            llSetLinkAlpha([LINK_SET, ALL_SIDES, 1.00], 0);
            llSetLinkPrimitiveParams(LINK_SET, [PRIM_GLOW,0.15]);
        }
    }
    timer() 
    {
        llResetScript();  
    }    
}

You are using the llSetLinkAlpha function the wrong way

 llSetLinkAlpha(LINK_SET, 1.0, ALL_SIDES);

Look here: http://wiki.secondlife.com/wiki/LlSetLinkAlpha

Edit: Your llSetLinkPrimitiveParams are wrong too, you should read the wiki. You forgot to give the face number with the glow.

Edit2: I see it now, you were doing it right in the first script you posted but then you changed things that were right. Here is how it should be:

default//Daytime
{
    state_entry()
    {
        llSetTimerEvent(200);
        vector sun = llGetSunDirection(); 
        if (sun.z < 0) state night;//This says, it's night time
        else//This is for if it's daytime
        {
            llSetLinkAlpha(LINK_SET, 0.0, ALL_SIDES);
            llSetLinkPrimitiveParams(LINK_SET, [PRIM_GLOW, ALL_SIDES, 0.0]);//Turn glow off
        }
    }
    timer() 
    {
        llResetScript();//Reset the script to see if it's still daytime  
    }    
}
//Everything uptop is the same as down here accept it's the opposite.
state night
{ 
    state_entry()
    {
        llSetTimerEvent(200);
        vector sun = llGetSunDirection(); 
        if (sun.z > 0) state default;
        else
        {
            llSetLinkAlpha(LINK_SET, 1.0, ALL_SIDES);
            llSetLinkPrimitiveParams(LINK_SET, [PRIM_GLOW, ALL_SIDES, 0.15]);
        }
    }
    timer() 
    {
        llResetScript();  
    }    
}
