Folks,

I have a layout something like this:

A BC D
2 4 6 ?
3 5 2 ?
4 2 3 ?
5 6 4 ?

I would like to be able to enter a reference to either Col A or Col B that would subtract the values in that column from column C and show the result in Col D.

Can anyone help me with how to do this?

Many thanks,
Alan

Round to nearest half hour?
Use =MROUND(A2,"0:30") to round to nearest half hour. Use =CEILING(A2,"0:30") to round to next half hour.
Hi, Alan,

is it this what you mean ?
  A  B  C  D  
1          A  
2 2  4  6  4  
3 3  5  2  -1 
4 4  2  3  -1 
5 5  6  4  -1

in column E, put the column letter that you want to use (ie. A or B)
in column D, put this formula:
Code:
=C1 - INDIRECT(E1 & ROW(E1))

then drag it down
result will be like this:
A--B--C--D--E
---------------
1--2--5---3--B
9--3--12-3--A
3--4--6---2--B

If the reference is always going to be one or the other an IF statement will do, but you will have to have column E to enter A or B

=IF(E1="A"),SUM(C1-A1),SUM(C1-B1)

If column E = A then it will take A away from C and put result in D you can validate column E to contain only A or B

HI,

changed my mind
you could use this
=C2-INDEX(A2:B2,1,$D$1)
(using same sample table as in my previous reply)
I prefer INDEX to INDIRECT

best regards,
Erik
