Simple notecard word counter

This is a simple script that will return the number of words in the first notecard object in inventory.

Drop a notecard into the container prim, then touch.

string sNote = "";
integer nLine = 0;
key queryID = NULL_KEY;
integer nCount = 0;

default
{
	state_entry()
	{
		llAllowInventoryDrop(TRUE);
	}
	
	on_rez(integer start_param)
	{
		llResetScript();
	}

	touch_start(integer total_number)
	{
		sNote = llGetInventoryName(INVENTORY_NOTECARD, 0);
		if(sNote != "") {
			queryID = llGetNotecardLine(sNote, 0);		
		}
	}
	
	dataserver(key query_id, string data)
	{
		if(query_id == queryID) {
			if(data != EOF) {
				nCount = nCount + llGetListLength(llParseString2List(data, [" "], []));
				nLine++;
				queryID = llGetNotecardLine(sNote, nLine);
			} else {
				llSay(0, "Notecard " + sNote + " contains " + (string)nCount + " words.");
			}
		}
	}
