[Script to initiate touch and to animate the mesh]

Hi,

I have tried for Linden scripting for animating a linked mesh.The mesh is animated and also a touch event is initiated .The code is below

integer total_prims;
integer link_counter;
string strNotecard;
default
{
    state_entry()
    {
        total_prims = llGetNumberOfPrims();
        llSay(0, (string) total_prims);
        llSetLinkAlpha(LINK_SET, 0.0, ALL_SIDES);
        llSetTimerEvent (0.2);
    }
    
    timer()
    {
        integer next_link_counter = (link_counter % total_prims) + 1;
        llSetLinkPrimitiveParamsFast( link_counter,
            [ PRIM_COLOR, ALL_SIDES, <1.0, 1.0, 1.0>, 0.0
            , PRIM_LINK_TARGET, next_link_counter
            , PRIM_COLOR, ALL_SIDES, <1.0, 1.0, 1.0>, 1.0
            ]);
        link_counter = next_link_counter;
    
         strNotecard = llGetInventoryName(INVENTORY_NOTECARD,0);
          if(llGetInventoryType(strNotecard)!=INVENTORY_NOTECARD)
           {
             llOwnerSay("There is no notecard in my inventory!");
        }
        else { 
            llOwnerSay("I have found a notecard called "+strNotecard+" and I will give that to whoever touches me.");
        }
    }
     touch_start(integer num_detected)
    {
        if(strNotecard){ 
        llGiveInventory(llDetectedKey(0), strNotecard); 
        }
    }
   changed(integer change) 
    { 
        if(change & CHANGED_INVENTORY){
            llResetScript();
        } 
}
}

 

The script is working fine but there is one problem !!

The  message  

I have found a notecard called "+strNotecard+" and I will give that to whoever touches me.

is coming repeatedly   .

How can i get out of this problem
