Attached is the file for reference.

I would like to FIRST, identify duplicated columns (in this case, they are column C and D, with "FY 2012" as its header). Those that do NOT have duplicate, leave them untouch (in this case, it's column B).

SECOND, for the columns that have duplicated headers, I would want to delete the column with the second header "original", but leave the data "restated" untouched
.
Essentially I want to write up a code that delete column D, but leaves columns A,B and C untouched.

How should I do that?
