I have a spreadsheet that tracks how far I hike in a given day. However, I
may do several shorter hikes in a day, and each one is tracked seperately.
Column A contains the date, column D contains the distance walked. If I do 3
hikes in a day, i have 3 rows, each with the same date, but the distance
walked is different.

So far so good. In cell F1 I put the same date, and i add all 3 hikes
together to give me a daily total.

Now day 2 comes along and i do 4 hikes, so now back to column A i have 4
more rows. Now in F2 i put in the 2nd date and tally up the total walked
that day. and on and on.

What I would like to find out is if there is a way to automatically do this
without manually doing it. Ie, I can manually enter the date in F1 and i
would want the total which appears in G1 to look at column A and see how many
rows that match the date, and then add the corresponding values in column D,
displaying the answer in G1.

What would be even better, is that I would not have to put the date in F1,
it would look at column A, and for every different date that shows up to put
each seperate date in F1, F2, etc, and then do the calculations.

I am not sure if this is something that can be done with formulas or would I
have to write a VB script.

Thx!
