Employee Attendance help please

Hi Guys,

I have the Excel Employee Attendance template that I slightly modified to suit my needs, but I'm struggling with the formula to calculate Days to carry over from previous year. I would like to calculate in tab SETTINGS how many days each employee used v's entitlement, and the result to be displayed beside each employee name. Could someone do me a Xmas present and help me with it?

I attached the file I was working on

Any help appreciated.

Kris.
