How can I type "CNA" into a cell in MS Excel 2002 without it changing my text
to "CAN"? I have even tried typing in 'CNA in the cell...and it still
changes it.

Even if I type the words "Policy CNA"...it still changes the CNA TO CAN.

Is this an auto-correct feature in MS and is there a way to disable the
auto-correct?

Thanks!
