Percentage Change to Selected Numeric Range

While not a stranger to IT, I have never delved into macros, or VBA so be gentle.......


I have several large multi-sheet spreadsheets with graphics, text, and numeric fields.

I would need to be able to modify a selected numeric range or block by a fixed percentage.

Example

before....................
abc 10
def 12
ghi 8

after........................ increased by 10%
abc 11
def 13.2
ghi 8.8


Do NOT want to copy, modify, and copy (values only) back!

Thank you!!!!!!!

wasnt sure which area was the most suitable - am desperate!
