Help with llDetectedGrab

Hey everyone,
I've been screwing around with llDetectedGrab and I'd though I'd see if I could make it so that if I dragged the mouse up the object would say up, and if I dragged it down the object would say down. It isn't going very well . Anyways, if someone could look at the code and fix it or tell me how to fix it, that'd be great! (I find an error at the if statements.)

string up = "<0,1,0>";
string down = "<0,-1,0>";


default
{
    touch(integer num_detected)
    {
        if(up > llDetectedGrab(0))
        {
        llSay(0, "Up");
        }
        else if(down > llDetectedGrab(0))
        {
            llSay(0, "Down");
        }
    }
}

Try this and you will be able to see what is going on:

default
{
	touch(integer total_number)
	{
		llOwnerSay((string)llDetectedGrab(0));
	}
}

Having said that......... llDetectedGrab's uses are really, really limited. In nearly every case you can script something much more reliable and sim freindly by not using it. Probably find it will be better to just use two buttons; up & down and use llDetectedLinkNumber with just one script.

Perhaps this workaround posted today by coincidence, may prove helpful. Seems llDetectedGrab has a bug:

Thanks for the code snippet there Jesse, but I'm still stuck on my original script. I'll try to get it to work tonight, but in the meantime, can someone point me in the right direction on how to fix it?

I looked at the example and I saw that llDetectedGrab returns vectors that are below decimals. I change it (the vectors at the top) to .1.

vector up = <0,.1,0>;
vector down = <0,-.1,0>;

default
{
    touch(integer num_detected)
    {
        if(up > llDetectedGrab(0))
        {
        llSay(0, "Up");
        }
        else if(down > llDetectedGrab(0))
        {
            llSay(0, "Down");
        }
    }
}

But I get an error at the 'if' and the 'else if' statements if I leave it as a greater than or less than. But if I change it to an equal sign, its fine. Anyone have a solution to this?
