I can see your answer to your original post on my news reader.
I posted a reply there, to your original thread.
I'll repeat it he

Try this in M15:

=SUM(M7:M8,M13:M14)
OR
=IF(SUM(M7:M8,M13:M14),SUM(M7:M8,M13:M14),"")

My apologies for posting as a new post but for some reason when I reply to
group its not getting there, so sorry if this duplicates along the way..

This is the formulas I am using....
This in M15.......... M7+M8+M13+M14
This in M7........... =CHOOSE(MATCH(D7,{0;5;7;9},1),"",150,200,"")
This in M8........... =CHOOSE(MATCH(H7,{0;5;7;11},1),"",150,200,"")

It is a form for renting properties if the renter puts in the dates inD7
and
H7 then M7 and M8 calculate the rental for those weeks. The problem is if
I
send a blank form with no dates entered it has #VALUE! where it would
normally enter the total in M15, the sheet works ok its just messy
sending
out a blank form with #VALUE! on it what I would like is for those
`error
messages` (#VALUE!) to disappear` if possible.

I hope this is a bit clearer
thanks
