    var number1 = $('.attendees input');
    
    // check if max populated
    if (max != '') {
      // set number1 max value

Hi Shameer,

I tried again with maxattendees also read-only and filled by formula, and noticed that the script actually works when value of table column changes, but doesn't work on the initial form load.

An easy workaround would be manually trigger 'change' event on the maxattendees field after initial form load. For example, added following script after Line 22

var event = new Event('change');
var element = document.querySelector('.maxattendees input');
element.dispatchEvent(event);

Hope it helps.

Hi Shameer,

The script seems still works for me when the field with attendees class is read-only and the field with maxattendees is editable. Could you elaborate on how it doesn't work on your side?

Hi ziyan Chen

In my Case , I need both field as read only , now if I make attendees Editable and maxttendees read only the script works , Maxattendees pull the value from lookup fileds , while attendees filed using the formula from a total value of table column , when I make both readonly the script is not working .I tried to using #Field_ID (Id value taken as q_ID , expample I make #Field21 when my filed value was q21) but that was also came as no luck ,
