Macro to Report Data Captured?

Hello guys, i am new to this site and need a hand. I am creating a wordbook that manages time reporting on projects worked. I will attach the frame of the document so far so you can understand it.
seriouslymessing.xlsx

So the first page is named Timesheet, where the user selects their name and projects worked on, plus the time spent on the project. This time is then normalised in the Calculations Page as required by my team for reporting. I have created the Normalisation calculations so thats ok. Where i require help is how to create a macro or code onto the "Save Hours" button on the Timesheet Page so that once clicked it automatically fills the available fields in on Sheet 2, with the data from the Calculations Page. Complex Right?
