What I'm trying to do is to have the following table:
Madrid 3 07/15/2011
Barcelona 4 07/19/2011
Rome 7 07/28/2011
So, the first two columns are filled in manually (first column is the place, the second column is the number of days I expect to stay there).
Now, I would like the third column to be filled in automatically by Google spreadsheets, which is the date I expect to arrive there. The first value (07/15/2011) would be filled in manually, but from there on, for example, the second row would grab the 3 days from the Madrid row, add it to 07/15/2011, and thus fill in the 07/19/2011 value automatically. That way, if say I end up staying a day more in Barcelona, the start date of Rome would automatically be shifted too (and all following dates).
Any ideas?
