Automate True-False Test on Long Column of Company Data

Hi

The attached worksheet is an example of a larger worksheet that contains the expenses for 3000+ companies. The columns represent the following categories: A(record number); B(organizational number); C (line number representing specific expense categories; D (salary ( line 100) and non salary (line 200) expenses); E Item value. The companies report up to 100 lines of data identified as lines 1-100. The last two lines, 101 salary and non-salary expenses end the data for each company. Each company reports salary and non-salary expenses for each line item; not all companies report every line or every category. I have used the true-false test =sum(E1:E100)=(E101:101) manually for smaller worksheets. I would like to automate this formula in some sort of a drag down fashion to run the test on a much larger worksheet.
Thank you for taking the time to read and consider this query.
