I want to be able to identify the credits and the possible invoices that can
be offset by account number. For example, line 4 above can possibly be
matched with line 2 or 3 but not line 13 (co jkl). I've tried a number of
combinations if vlookup with IF(and) and can not seem to get it to work. If
have even created another column using =IF(E1<0,e1*-1," ") which gives me an
exact figure to match to but I can not seem to make it work. Can you help?
Thanks.
