Last_column & autofill help....
 

Hello -

I've been searching this forum for help and while I've found bits/pieces of
useful code, I'm not sure how to put it all together. Here's what I need to
do:
** find last column with data
** delete two columns, one column from the end
- Ex if sheet has 10columns, delete #8 & 9
** in the first blank column, insert fomula (starting 4th row down) and
autofill to last row AND THEN one more row
** then total the values in two columns
- Ex if sheet has 10col, total #6 & 7
** copy/paste_values the inserted formulas

Can you please help me build this code?

Thanks!
Ray
