count items in colum using aggregate record

count items in colum using aggregate record

I am tracking apartment complex units that have been cleaned.   I have a dropdown field with the following values:   3 – BDR and 4 BDR units. My end goal is to get a count of how many 3 –bedroom units and 4 bedroom units in the column. How would accomplish this using an aggregate record task?

Example 4 - BDR Units = 10


                 3-BDR units = 7

Thanks
