add page numbers via script

[hilukasz]

I want to try to add page numbers to artboard based on position of selected text. I saw someone had made a script similar to this, but I need to do it based on selected text. Here is my solution, but for some reason it is not adding it based on artboard coordinates. I ran into this a while ago, and setting the rule to artboards fixed it, here it does not seem to have same effect.

#target illustrator
// global variables
////////////////////////////////////////////////////
// Set up varaibles
////////////////////////////////////////////////////
var pageNumber = app.activeDocument.artboards.getActiveArtboardIndex() + 1,
    doc = app.activeDocument;
//make sure only 1 item is selected
if(selectedItems.length > 1 || selectedItems.length < 1) {
    alert('please select only one item'}
else { 
    var selectionTopPosition = doc.selection[0].top,
        selectionLeftPosition = doc.selection[0].left;
    doc.selection[0].remove();
    doc.selection = null;
    //remove selection
    //alert(selectionLeftPosition+" "+selectionTopPosition);
}
//create page numbers layer
var pageNumbersLayer = doc.layers.add();
pageNumbersLayer.name = "page numbers";
var pageNumbersLayerGroup = pageNumbersLayer.groupItems.add();
// main loop
//loop through artboards 
for(i = 0; i < app.activeDocument.artboards.length; i++){
    app.coordinateSystem = CoordinateSystem.ARTBOARDCOORDINATESYSTEM;
    doc.artboards.setActiveArtboardIndex(i);
    alert('active artboard is '+i);
    var pageNumber = doc.artboards.getActiveArtboardIndex() + 1;
    var pageCount = i + 1;
    var textRef = pageNumbersLayerGroup.textFrames.add();
    textRef.contents = pageCount.toString();
    textRef.top = selectionTopPosition;
    textRef.left = selectionLeftPosition;
    pageCount++;
}

Have you tried to set the coordinate system for the specific doc.

Actually it worked for me with this

doc = app.activeDocument;

selectedItems = doc.selection;

I started with a single string (text) at the number location on artboard 1.

oh wow, I'm a dummy! I somehow forgot to add that variable back in when I was piecing it together since I was testing it in pieces. thanks for the extra set of eyes! fixed it.

also I had to push the line:

app.coordinateSystem = CoordinateSystem.ARTBOARDCOORDINATESYSTEM;

into the first conditional, this is what was originally messing it up. I realized I got the position too late with wrong coordinate system. works perfect now.

How can I get my script to note artboard coordinates and not document coordinates? This solves my problem, thank you.
