Did you look for it by yourself? Expecting such things from us is not a good practice.
Once again, it does not work like this here.
Here is what is expected of enquirers:

2. Formulate what was done by you that looks like an issue/not working.
Try them and tell if you face issues.
Members will be more than happy to help like this.
