Hi

How do I get Excel to apply a certain formula (held in a central table)
based on particular values in the same row? I don't want the actual result
of the formula whilst it's in the central table, as this will be different
when pasted into each row.

Example, (where Col D is the place I want the formula from the central table
to be applied to):

Central table:
[Row 1] = A1+B1 (Apply this if column C equals the word "Rule 1")
[Row 2] = A1-B1 (Apply this if column C equals the word "Rule 2")

Spreadsheet:
Col A Col B Col C Col D
1 1 Rule 1 2
2 2 Rule 2 0

Thanks
Arjay
