writing excel formula

Hi,

How do we write excel formula with relative address and when looping for each row?

For example: cell C =cell B* cell A, where:
B is 1 cell to the left from C and A is 2 cells to the left from C.

Thanks,
Chris

Add a new variable CellA (Number)
Add a new variable CellB (Number)
Add a new variable CellC (Number)
Extract value of cell A into variable CellA
Extract value of cell B into variable CellB
Add an Assign Variable Step.  Value will be Expression.  Variable will be CellC.  Expression is CellA*CellB.
Right-Click on Cell C.  Select Set Content of Cell.  Click drop-down box next to Content and Select Variable.  Select variable CellC.
