This Script Works for Indesign 2025 on Windows but Does not Work for 2021 On Mac

Hi @hector_2413, Not sure if this helps, here’s your dialog using the dialogColumns class—the results get passed to the main() function:

var f, t, z, p, pre, ic, fn;
makeDialog();
function makeDialog(){
    var theDialog = app.dialogs.add({name:"Enter a Number", canCancel:true});
    with(theDialog.dialogColumns.add()){
        staticTexts.add({staticLabel:"From:"});
        staticTexts.add({staticLabel:"To:"});
        staticTexts.add({staticLabel:"Leading Zeros:"});
        staticTexts.add({staticLabel:"Prefix (e.g., https://www.xymo.co/p/078873-05|050725|):"});
        staticTexts.add({staticLabel:"Prefix Font Size (pt):"});
        staticTexts.add({staticLabel:"CSV File Name (no extension):"});
    }
    with(theDialog.dialogColumns.add()){
        f = realEditboxes.add({editValue:1, maximumValue:1000, minimumValue:1, minWidth:100});
        t = realEditboxes.add({editValue:1000, maximumValue:5000, minimumValue:0, minWidth:100});
        z = realEditboxes.add({editValue:4, maximumValue:5, minimumValue:1, minWidth:100});
        pre = textEditboxes.add({editContents:"", minWidth:150});
        ic = integerComboboxes.add({stringList:["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13"], editValue:10, maximumValue:100, minimumValue:0, smallNudge:1, largeNudge:10, minWidth:100});
        fn = textEditboxes.add({editContents:"qr_codes", minWidth:150});
    }
    if(theDialog.show() == true){
        f = f.editValue;
        t = t.editValue;
        z = z.editValue;
        pre = pre.editContents;
        ic = ic.editValue;
        fn = fn.editContents;
        main()
	}else{
        theDialog.destroy();
    }
}

/**
* Script to run.
* @ return void 
*/

function main(){
    alert("Results\rFrom: " + f + "\rTo: "+ t+ "\rZeros: "+ z + "\rPrefix: "+ pre+ "\rFont Size: "+ ic+ "\rFile Name: "+ fn);
    //script code here
}

this Script I made for creating .csv files froms Indesign

Hi @hector_2413 , Generally I use InDesign’s built in dialog class for simple dialogs like yours, so I can’t help with your code. See the API Dialog, DialogColumn classes.

I also get the error using CC2021.

For building ScriptUI class dialogs I use this great online dialog builder:

HFS / POSIX paths problem? 

On my side, while running your original version, both on Mac (2024, 2025) & Windows (2024), I get the following error:

The problem is you can't modify a doc while the modal dialog is open.
Here's my version:

#target indesign

makeDialog();

function makeDialog() {
	var dlg = new Window("dialog", "Generate QR CSV for SmartStream");

	dlg.orientation = "column";
	dlg.alignChildren = "left";

	dlg.add("statictext", undefined, "From:");
	var fromInput = dlg.add("edittext", undefined, "1");
	fromInput.characters = 10;

	dlg.add("statictext", undefined, "To:");
	var toInput = dlg.add("edittext", undefined, "1000");
	toInput.characters = 10;

	dlg.add("statictext", undefined, "Leading Zeros:");
	var zeroInput = dlg.add("edittext", undefined, "4");
	zeroInput.characters = 10;

	dlg.add("statictext", undefined, "Prefix (e.g., https://www.xymo.co/p/078873-05|050725|):");

	dlg.add("statictext", undefined, "CSV File Name (no extension):");
	var fileNameInput = dlg.add("edittext", undefined, "qr_codes");
	fileNameInput.characters = 30;

	generateBtn.onClick = function () {
		// the vars in this handler are global to make them available in the main function

	dlg.center();

Hi @hector_2413 I'm running MacOS 15.4.1, Indesign 20.3.1 and your script worked okay as far as I could tell. It generated a csv file with my test input. What error do you get on Mac?
