      const myObj = {"name": "Dave", "age": 38, "country": "England"};
      
      // To add something new you can use dot notation
      myObj.newKey = newValue;
      
      // Or you can use bracket notation - only really needed if you have spaces in the key or are using a variable to hold the key
      myObj["newKey"] = newValue;

      AttackTablePresets.insert(newPreset);

      This is for arrays, not objects. I think Lindon confused you :)

          @Chazrox It's not a function, it's accessing the property of the object.

          Just like when you use .length to find out how many characters are in a string or elements in an array. If it doesn't have () at the end then it's not a function.

              I combined everything to try to do everything at once..

              1. export table state
              2. push new preset to 'AttackTablePresets'
              3. push 'name' to combobox.

              this is working so far...but my presets in the combobox keep disappearing every couple of times I press save.

              Screenshot 2025-07-09 at 5.55.29 AM.png

              see it saved a few presets, but at some random point it just dissapears.

              // SAVE PRESET BUTTON CONTROLS
              inline function onSaveOkControl(component, value)
              {	
              	local f = FileSystem.getFolder(FileSystem.Desktop).getChildFile("myFile.json"); 
              	f.writeObject(AttackTablePresets);
              	
              	if (value)
              	{
              		
              		local tableData0 = TableEnvelope1Pro.exportAsBase64(0);
              		local presetNameNOW = PresetNameToSave.get("text");
              
              		AttackTablePresets[presetNameNOW] = tableData0;
              		
              		local keyList = [];
              		
              		for (k in AttackTablePresets)
              		{
              			keyList.push(k);
              		}
              		
              		PresetList.set("items", keyList.join("\n"));
              	}
              };
              Content.getComponent("SaveOk").setControlCallback(onSaveOkControl);

                    Edited because I forgot to declare the tables in the example.

                      So this is what I'm seeing.

                      • You click save
                      • You write the presets object to a JSON file - you have this outside of the if statement so this happens on both button on and button off
                      • You grab the table data and add it to the object
                      • You repopulate the combo box list.

                      I don't see an issue with the list being reset when clicking the save button, but I don't see anywhere you are loading the presets back from the file, so the combobox will clear on compile.

                      Also you probably want to save the object to the file after you've added the new value.

                            Write out in English step by step what behaviour you want. Then we figure out how to translate that into code.
