I have a CGI script used to retrieve or alter values of database tables and then output the results by generating a table in html.

Using CGI.pm, I was able to store the previous selection each time a new request is made. However, I was unable to achieve a cummulative retention of the results.

eg:

1st request is to retrieve all entities of Column 1

2nd request made to retrieve an entry in (2,3)

After the 2nd request, the entry(2,3) is shown and Column 1 values will be gone since the page has been refreshed.

I am showing the request form and the corresponding table on the same HTML. One way of doing this is to use hidden field to store the current results and pass it together with the next request, but this method is cumbersome when I have a 10X200 table

Any help will be greatly appreciated.
