Mike,
Thanks for the help, however as I am not a Excel programmer I may have misunderstood what you meant. Based upon your solution my complete statement now looks like this:
=If(isblank(d16),"",SUM(G16-(H16+I16+J16))=0,"$0.00",SUM(G16-(H16+I16+J16)))
Excel claims there is an error in this formula but it does not suggest how to correct it.
Would you provide a little help?
Thanks
Al
