The input type for mobile number in two pages

[yasminove]

I noticed you're using input type="number" for your Mobile number on Add Participants and Add Manager pages.

Using input type="number" may result in some values added as a mobile number while they are not valid ones.

You might want to change it to:

<input type="tel"
       pattern="[0-9]{3}-[0-9]{3}-[0-9]{4}"
       required>

This means your receiving the user's mobile number in the format xxx-xxx-xxxx

You might also want to add some validation ⭐️
