VBA referring to a different sheet, automatically fill cell based on content of other cell

OK, I tried this and it did not work, every time I ran it, excel tried to use the I column in itmof and not itbof. It still didn't do anything in the I column of itmof because there is no data there but every time I ran it the entire I column in itmof was highlighted. I think if you can get it to go to the itbof tab, then column I will successfully be rounded to 5 decimal places!

OK. Try replacing this line:

Range("I2:I" & bottomA).Select

with this line:

Sheets("itbof").Range("I2:I" & bottomA).Select
