~Setting an integer using note card line ~

I've been trying to set an integer using a note card line, and using error checking to make sure whats in the note card is numbers, and not letters.
Any ideas what's wrong, here's an example of the part of the script that does it.

pri is a string: pric is the integer I dump to: mo is the integer I'm trying to get the value on the note card to.

pri = llGetNotecardLine("Price",0);
        pric = (integer) pri;
        
            if (pric > 0)
            {
                mo = pric;
            }

What problems do you encounter with it?

Without knowing anything about the issue I would say to make sure that the line has nothing in front of actual numbers, as casting a string to an integer works on the basis of the first numeric character to the one before the next non-numeric one, i.e. if there are spaces in front of it it will evaluate to 0. But that probably isn't the issue.

It reads as "0", regardless of the number I put on the first line of the script.

Well, it shouldn't, if it is reading the line properly.

Try putting in a llOwnerSay("pri='" + pri + "'"; line to check that there are no extra spaces etc.

If 'pri' doesn't begin with an integer then (integer)pri will return 0.

However, as your code stands it makes no sense. llGetNotecardLine triggers the dataserver event it does not in itself return the contents of the notecard line. It returns the key that will be supplied to the dataserver event as its queryid parameter.

Try this:

key note_key;//key of data request

default {
	touch_start(integer total_number) {
		note_key = llGetNotecardLine("Price",0);//"Price" is name of notecard
	}
	dataserver(key requested, string data)
	{
		integer price = (integer)data;
		llOwnerSay((string)price);
	}
}

Notecard named "Price"

50

When touched this says:

Object: 50

Yes, blast it, I was too held up by the details of parsing to notice that; apologies. It may well be just an lack of proper use of the dataserver.
