Trying to create a button to save as new sheet and name Rota wc 12.12.12 (Date changes)

Hi Guys,
I was wondering if someone could help me out as i am sitting over this for about 4 days now and cant seem to find a solution.
I am trying to create a rota system where i have created a Source Page with Staff names and their hrly pay and a date range which is the data for my Master Sheet drop down box.
What I would like to do is chouse the date from the dropdown box and enter the rota on the master sheet.
Then I would hit my Save button and and it would create a copy of the master sheet and save it in a new sheet called Rota wc [the Date chosen from the drop box] . If someone could help me that would be great as i am a newbie to programming.

Thanks in advance

Have attached a copy of what i have so far.
Even if someone could just point me into the right direction, would be greatly appreciated.
