General :: How To Add A Field That Counts The Number Of Qualifiers Per Race


I am new to using access but have managed to build a database that I use to find qualifiers for horse racing based on stats I import for all the racers in the days racing. I have a query which shows the date, time, track, horse and trainer but some races have more than 1 selection so I want to add a field that counts the number of qualifiers per race. I am finding it hard to do a countif, date AND time & track are all the same within that query.

I also want to add another show the total runners in the race but this will have to look into the tables where the query is run from. Hopefully I can figure this out when I find out how to solve my original problem.
