Script to scale text frames based on certain paragraph style ( page range )

Ok, here you go:

function getData () {
  // Create a dialog
  var myDialog = new Window("dialog", "Scale Text Frames");
    myDialog.orientation = "column";
    myDialog.alignChildren = "left";

  // Function to get paragraph styles
  function getParagraphStyles() {
    var styles = app.activeDocument.paragraphStyles;
    var styleNames = []; // Default "None" style

    for (var i = 1; i < styles.length; i++) {
    styleNames.push(styles[i].name);
    }

    return styleNames;
  }

  // Paragraph Style Dropdown
  var stylePanel = myDialog.add("panel");
    stylePanel.text = "Paragraph Style:";
  var styleDropdown = stylePanel.add("dropdownlist", undefined, getParagraphStyles());
    styleDropdown.selection = 0;

  // Page Range Input
  var pageRangePanel = myDialog.add("panel");
    pageRangePanel.text = "Page Range (e.g., 1-5):";
    var pageRangeInput = pageRangePanel.add("edittext");
    pageRangeInput.text = "2-3";

  // Scale Factor Input
  var scalePanel = myDialog.add("panel");
    scalePanel.text = "Scale Factor (%):";
    var scaleFactorInput = scalePanel.add("edittext");
    scaleFactorInput.text = "150";

  // OK and Cancel Buttons
  var buttonGroup = myDialog.add("group");
    var okButton = buttonGroup.add("button", undefined, "OK");
    var cancelButton = buttonGroup.add("button", undefined, "Cancel");

  pageRangeInput.onDeactivate = function () {
    if (!/^\d+-\d+$/.test (this.text)) {
      alert("Invalid page range format. Use 'start-end', e.g., '1-5'.");
    }
  }

  if (myDialog.show() == 2) {
    exit();
  }

  return {
    selectedStyle: styleDropdown.selection.text,
    pageRange: pageRangeInput.text,
    scaleFactor: parseFloat(scaleFactorInput.text),
  }

}


function scaleFrames (d) {
  app.windows[0].transformReferencePoint = AnchorPoint.CENTER_ANCHOR
  var startPage = parseInt(d.pageRange.split("-")[0]) - 1;
  var endPage = parseInt(d.pageRange.split("-")[1]) - 1;
  var pages = app.documents[0].pages.everyItem().getElements();
  
  function scaleFramesSub (frames) {
    for (var i = 0; i < frames.length; i++) {
      if (frames[i].paragraphs[0].appliedParagraphStyle.name == d.selectedStyle) {
        frames[i].horizontalScale = frames[i].verticalScale = d.scaleFactor;
      }
    }
  }
  
  for (var i = startPage; i <= endPage; i++) {
    scaleFramesSub (pages[i].textFrames.everyItem().getElements());
  }
}


var data = getData();
scaleFrames (data);
