The code captures those lines ticked. if I "Next Page" I can select more. To enable "many" lines to be selected I'm having to split the JSON created between paging forward and backwards. Adjusting what you kindly gave me yesterday allows me to add chunks that I can pick up when I page between. However I just noticed that if I selected 3 then page forward select 1, page back, I only see 3 in the params despite the fact the code picks up all 4 selected and attempts to create the field and populate it. Kinda hard to explain and over 1200 lines of SS1.0 code.
