I am in the process of developing a system that will notify users in the office when a specific individual is busy and cannot answer the phone.
How can I implement a feature where clicking "engaged" changes the color of the availability box to red on their screen and updates it simultaneously for others?
I currently have a functional prototype, but it relies on .vbs to change the CSS file through find and replace, making it an HTA app. I would like to transition it to an HTML page instead.
