Reading from 2 notecards in 1 script?

Is it possible to read from 2 different notecards in 1 script? If so how?

You need to clarify Your question please in order to get a specific example.
But the short, and not so helpful, answer is Yes, it is possible to read from two different notecards in the same script

Yes. The below code sniplet "should" do the trick, although it is non-tested and could blow up and kill all your neighbor's pet hippos:

key notecardreq1;
key notecardreq2;
integer notecardline1;
integer notecardline2;

default
{
	state_entry()
	{
		notecardreq1 = llGetNotecardLine("notecard1",notecardline1);
		notecardreq2 = llGetNotecardLine("notecard2",notecardline2);
	}
	dataserver(key query_id, string data) 
	{
		if (query_id == notecardreq1)
		{
			if (data != EOF)
			{
				++notecardline1;
				// DO STUFFS
				notecardreq1 = llGetNotecardLine("notecard1",notecardline1);
			}
			return;
		}
		if (query_id == notecardreq2)
		{
			if (data != EOF)
			{
				++notecardline2;
				// DO STUFFS 2
				notecardreq2 = llGetNotecardLine("notecard2",notecardline2);
			}
			return;
		}
	}
}

Those were...hippos?
