Hello,
I am very close to getting this pagination to work. The first page is fine, but then when I click on the hyperlinks for the next pages, the results are blank. After reading other threads where people have had the same problem, it appears that it is a result of a variable not being passed through to the next pages.
However, I have the variable “find” as both a session variable and an addition to the URL of the next pages, and the next pages are still blank. Any ideas why it might not be working? Is “find” the right variable for me to be passing through to the next pages?
Thanks,
John
