Following is the information available:
Data is manually entered into Columns A, B as it comes from three different
sources. C gives total of A and B, whereas D totals Column C for a day.
On second day, fresh data is entered from Row 4 downward. Column D
starts totalling Column C for next day only.

Sheet1

A B C D
1 20 25 45 45
2 18 14 32 77
3 2 22 24 103 DAY 1
4 25 10 35 35
5 10 15 25 60 and so on.

What I am looking for is to have a grand total in another worksheet (may or
may not be in same file), where only Total figure at the end of day shall be
entered.
Each days final total shall be entered one below other automatically and
shall be totalled. The input shall have to be last filled value from sheet 1
column D, whenever date changes.
Kindly help
