=PRODUCT

[billy-bob]

i'm trying to generate an automatic form (which will locked down)
within the hiden E columm if have a list of numbers, so when i pick 'p'
(this is a tick mark in wingdings) from a drop-down in columm C, it
automatically aprears in columm D as choosen.
at the bottom of the form all choosen items in columm D need to be
multiplied altogether so i used the product formula -
=PRODUCT(D3060)
However because not all of the items in the columm can be choosen at anyone
time - it was coming up as a blank cell - so after looking through this site
I tried this -
=IF(OR(D4561=0,D45:E61=""),"",PRODUCT(D4561))
to elminate the possible zero being generated
it still doesn't work and i'm at a lost
can anyone help!

Maybe

=IF(OR(count(D4561)=0,D45:E61=""),"",PRODUCT(D4561))

I'm sure there is a more elegant solution, but this works:

=SUMPRODUCT((D4561<>"")*(D4561<>0)*PRODUCT(D4561))/SUMPRODUCT((D4561<>"")*(D4561<>0))

Hope this helps,

Hutch

thanks for post. it works but... when one or more of the figures in the
D45-D61 is removed or blank - to cell comes back blank. this is the problem
i'm looking to resolve.

thanks tom for post
it did work
i found the problem i was having was was in the formula in D45 to D61
it was
=IF(C49="P",E49,)
this was returning this cell as zero (althrough show as blank), so i changed
all these cells to
=IF(C49="P",E49,"")
and it's all working ok now (yip-hee)
thanks for the help.

thanks bob for post
it did work
i found the problem, i had the wrong formula in D45 to D61 it was
=IF(C49="P",E49,)
this was returning this cell as zero (althrough show as blank), so i changed
all these cells to
=IF(C49="P",E49,"")
and it's all working ok now with just the product formula alone (yip-hee)
thanks for the help.
