How to scale selection - from center - based on Selection?

Question

I have a snippet that gets the width of the current selection and scales a named path by percentage or set amount. But I don't know how to make it scale from the CENTER. It only scales from the left. I also tried "resize" but could not get it to work at all. What am I doing wrong?

var aDoc = app.activeDocument
var myItem = aDoc.selection[0];
var dimensions = {"width" : myItem.width, "height" : myItem.height};
aDoc.pathItems.Divider.width = myItem.width+20 //add points
//aDoc.pathItems.Divider.width = myItem.width*1.20 //by percentage
//~ aDoc.pathItems.Divider.resize(
//~ myItem.width*1.1, //x
//~ 100.0, // y
//~ false, // changePositions
//~ false, // changeFillPatterns
//~ false, // changeFillGradients
//~ false, // changeStrokePattern
//~ false , // changeLineWidths
//~ Transformation.CENTER); // scaleAbout

The "Selection" is the text. I want to scale the "Divider" line based on the width of the Text. My original script DID allow a calculation (aDoc.pathItems.Divider.width = myItem.width*1.2) but scaled the line from the left.

Using "resize" method does not seem to allow for "Calculations". Is that correct?

Salut !

var aDoc = app.activeDocument

var myItem = aDoc.selection[0];

var Divider = aDoc.pathItems[0];

scale = myItem.width/Divider.width*100;

Divider.resize(scale,100);

I realized when implementing this script that it was not actually targeting the path by name and could therefore select a path on a layer above. I've changed it slightly so it targets the specific path named "Divider".

var aDoc = app.activeDocument
var myItem = aDoc.selection[0];
var Divider = aDoc.pathItems.getByName("Divider");
scale =  myItem.width/Divider.width*100+8;
Divider.resize(scale,100);
