Queries :: Auto-count Once Updated

i have a table with a column that reflects the below info, need to work out something for access to keep a count on the numbers of fields, have tried using conditional "count" in queries, the resultant value return is 12, this count omits counting all the "1", which is not i wanted, how do i tell access to start counting from the most recent "1" onward, and in this case the correct count value should return as "5", meaning there are 5 fields being entered after the most recent "1".
