[mso] Formula to not give "#DIV/0!" results

Good afternoon Genius Excel Group (GEG),
Sorry for this simple question but again I'm seem to be stuck on something that
shouldn't be all that difficult.
Problem:
Part 1:
There are 4 columns of data that are entered manually for % residual recipient
alleles for Bone Marrow Transplant patients. That formula is simple enough
"=(B14+C14)/(B14+C14+E14+F14)" this gives me a decimal fraction between 0 and
1. However, there are 16 alleles tested for from the patient's bone marrow to
see what alleles from the recipient are still in the marrow and not all alleles
are found. How can a formula be written to NOT give the #DIV/0 results if
there when none of those alleles are found? It must have something to do with
an IF statement but I have tried several permutations with no success.
Part 2:
I need the above result to populate another cell on the work sheet that gives
me an average of individual marker % residual recipient. The average part is
easy and the formula works fine if I type in the numbers. I tried to write an
IF formula to complete this:
=IF(H14>0,H14,"")
but I'm not sure if this is how to write it. What I would like the cell to
"do" is look at the result from the above problem and IF the result is >0, then
put the result from that cell in and if the cell has anything else in it just
leave it blank. If I leave it blank I won't have to change the formula for the
average already written. If there is a 0 in there it will throw off the
average.
Sorry if this is confusing.
Any help would be greatly appreciated.
