I am using =NETWORKDAYS(B23,B29)-1 as one of my formulas. I have the -1
because I am tracking several different time frames going from one place to
another and without the -1 it is counting a day twice. I need this formula in
every cell that has the days, but there won't be a time span every time. When
there's no time span i get a -1 in the cell which is messing up count. Is
there a way to add an IF function to the function above that says If -1 then
skip? or count as 0? I've tried several different ways and it's not working.

Thanks
