Adding or Subtracting based on 3 variables

This may be simple but I'm new to formulae in Excel.



I've got two sets of data that both have Dates in one sheet. One set has repeated dates for every Type and every State because it's a cumulative summed frame which looks like:



Date          State     Type      Value 1
2010-01-01 AK NUC 10
2010-02-01 AK NUC 10
2010-03-01 AK NUC 10
.
.
2010-01-01 CO NUC 2
2010-02-01 CO NUC 2
.
.
2010-01-01 AK WND 20
2010-02-01 AK WND 21
.
.
2018-08-01 .......


What I need to do is take a second set and add based off the 'Operating Date', to each 'Type' and 'State' and then subtract based off the 'Retirement Date' all with respect to the original 'Date'. The second set looks like:



Operating Date   Retirement Date   Type    State       Value 2
2010-02-01 2010-04-01 NUC AK 1
2011-02-01 2014-02-01 NUC AK 2
2011-03-01 2016-03-01 NUC AK 10
.
.

.
2018-08-01 .......


My logic for the example on AK the output would add and subtract like:



if AK(Date) == AK(Operating Date):
AK(Value, Date) = AK(Value, Date) + AK(Value, Operating Date)

elif AK(Date) == AK(Retirement Date):
AK(Value, Date) = AK(Value, Date) - AK(Value, Retirement Date)
else:
continue


And the actual output data (just for AK 'NUC') would be:



Date          State     Type      Value
2010-01-01 AK NUC 10
2010-02-01 AK NUC 11
2010-03-01 AK NUC 11
2010-04-01 AK NUC 10
.
.
2011-01-01 AK NUC 10
2011-02-01 AK NUC 12
2011-03-01 AK NUC 22
2011-04-01 AK NUC 22
.
.
2016-01-01 AK NUC 22
2010-02-01 AK NUC 22
2010-03-01 AK NUC 12
2010-04-01 AK NUC 12

How can I go about doing this type of operation in Excel?

  • Basically it's just saying that it will add the value on the Operating Date and then subtract it on the Retirement Date. So you see on 2010-02-01 the first Operating Date for AK in type NUC is of Value 1 so it is added on the first set as 10+1 = 11 but then the Retirement Date of that same Value is on 2010-04-01 so then on that date it is removed as 11-1 = 10.
