How to get last numerical value in a row that contains numbers and characters|General Excel Questions & Answers|Excel Forum|My Online Training Hub

In H5 I am trying to figure out how I can get the last numerical value in row 3 (and always get the last numerical value in that row, as data will eventually be added in G3:K3).  This is for tracking bloodwork.  F3 is the current last entry in the row, but it is a character instead of a number.  I'd like to leave that character there (or replace it with something that would indicate there is no numerical value there, without leaving it completely blank).  The "-" was put there to indicate the bloodwork was not run on that date.  The current formula I was able to find just returns the last entry, not the last numerical entry.
