Hi,  I am trying to do a formula that will either return a percentage or
if either of two cells are blank, then I want it to return either a "0"
or "n/a".  Here is my formula   =(J5/H5)-100% (this gives me the
recipacal of the percentage).  It works fine.  Now what do I add to get
it to return either "0" or "n/a" if either J5 or H5 is blank or both are
blank?  Hope this makes sense.  Background - I am trying to divide one
number by another to get the percentage of the difference 8/10-100%=20%
but if there are no numbers in the cells and nothing to divide, then I
want it to return "0" or "n/a".

Thanks.
