Putting identifier when number of rows equals 37

Hi Guys,

Maybe somebody is going to help me with the following problem:
I was hoping in the worksheet attached:
Column J or K. can have a formula that can Identify if -> Colum H total is not equal to 37; and if Colum H total is 37 to place an identifier on each of the rows. These are actually small tables within one tablee, with number of rows summed up for each small table. I want to have highlighted those rows that add up to 37 in each small table. I hope you got my point
Many thanks in advance for your ideas and suggestions!
