in a cell to overwrite itself. Makes sense?
But you can program a macro to find the last filled cell in a column and do something with it (like putting it in a certain place).
Personally, I would write a custom function to do the calculations and call that function in the cell next to F16, F17 and so on. Something like =mytotalcosts(F16) and drag that down.
Every Saturday I record the readings from my Electricity & Gas meters in a spreadsheet which I use to calculate that weeks usage.
Week 1 reading for Gas goes into Cell E10, week 2 into E11 Week 3 into E12 and so on through to week 52.
In cell F11 I have put the function =(E11-E10) and filled down this formula down the column which produces the number of units used that week.
After 52 weeks I use Auto-sum to give a total for the year.
I do the same for Electric
On sheet 2 of the workbook I have set up a calculator that takes the value from column F each week, and using the conversion calculation provided by the power company to convert Units to Kilowatt hours and then multiply this by the cost per KwH. Standing charges and taxes are also added at the appropriate stage, giving a final total cost for the energy used each week.
At present I have to copy the weekly unit used into the calculator manually. The figure is copied from column F and pasted into Cell D10 in the calculator.
What I want to know is, is it possible to put a function in Cell D10 in the calculator so that the Units used figure is placed there automatically each week? If the Cell Address remained constant it would be simply a matter of putting ='Meters-10'!F16 in Cell D10 but as the following weeks reading would be in F17 this would not work. How do I tell Excel to use the value in the latest row in column F?
