Solution for this topic

We have to answer all the questions asked by every user every day and can’t assign dedicated support person for each user.

What you are trying to achieve needs custom code as currently theme doesn’t provide this functionality. Developing custom code for custom functionality is beyond the scope of support that we provide here but still we try our best to help users.

The code i have provided is working fine on my test site but not sure why it is not working for you. As your site is hosted locally which is making hard for me to troubleshoot it.

So please try using following various code solutions or contact me when your site will be accessible for me.
