while I create a multi column sumif function as this:
=sumif(a:a,"special",or/and(b:b,d:d,f:f)), but it is unable to function. So, I use the duplicate sumif function like this:
=sumif(a:a,"special",b:b)+sumif(a:a,"special",d:d) +sumif(a:a,"special",f:f).

Please tell me how to simplify it with thanks.
