Hi
1) =IF(C3="",TODAY()-B3),C3-B3. This is meant to calculate the
elapsed time
between C3 and today if B3 is blank - but doesn't
What does it return?
Are you sure C3 is Null and not a SPACE " ", or a 0 with
ToolsOptionsViewZero values unchecked?

Option 1: =IF(AND(AD78="80",N78="Scrap/AV",""),AD78="DVLA",$AE$2)
should be
=IF(AND(AD78="80",N78="Scrap/AV"),AD78="DVLA",$AE$2,"")


Option
2:=IF(N77="","",IF(AD77=80,"",IF(AND(N77="DVLA",AD 77=""),$AE$2)))
should be
=IF(N77="","",IF(AD77=80,"",IF(AND(N77="DVLA",AD77 =""),$AE$2,"")))

a) carry-over to a new worksheet, vehicles that remain unclaimed
Take a look at Advanced Filter
Debra Dalgleish has some great guidance on her site

b) reset the clock to accumulate the next months' storage charge.
you don't say what the clock is?
Presumably a cell on the sheet which holds reference date.

There are several strings to this question.

1) =IF(C3="",TODAY()-B3),C3-B3. This is meant to calculate the

2) The formulae work OK except they return FALSE when cell N78 (DVLA
cell)
has anything other than DVLA.
Option 1: =IF(AND(AD78="80",N78="Scrap/AV",""),AD78="DVLA",$AE$2)
Option
2:=IF(N77="","",IF(AD77=80,"",IF(AND(N77="DVLA",AD 77=""),$AE$2)))

3) Invoices are raised every month for vehicles kept in store. Two
things;
I need to a) carry-over to a new worksheet, vehicles that remain
unclaimed
and in store. and b) reset the clock to accumulate the next months'
storage
charge.

Finally. When this has all been piloted for a month or twoI want to
migrate
it to MS ACCESS so that data can be kept clean. Does anyone know
whether the
Excel calculations migrate to Access?
