Hello, I have a table that has 2000 rows and 8 columns. The headings of columns are: yearjel.code.1jel.code.2jel.code.3jel.code.4jel.code.5jel.code.6 jel.code.7. Under each column, there are either numbers or blank spaces corresponding to the given year. For instance, my 10th row is:1019838242824382609170 I want to count how many times each code appears in total and how many times it appears in each year. I don't think I can use table function. What can I do?
Sincerely, Yosub Jung.
