Tighten, Improve, and Perform

Hello everyone!

New to the community. I was looking for some assistance on a mock pay datasheet I've started working on for a class I finished but found myself interested on improving my project. Relatively new to excel and learning many useful things each day! I ran into something I needed some expert help on. On my weekly hour calculator sheet, I wanted to someone store data when an employee inputs their times on the hour tables. I want to be able to have a list of each pay period so employees can go to the list and select which pay period they want. I also needed help with making the tables look and function much better. I am still learning, and really want to understand how to make things more fluent and proficient.

Any help with anything, even just input and small adjustments would be amazing!
Thanks everyone!
