Hi everyone,

I'm using a .csv file as the basis for a spry dataset. I've got it working and the data is getting inserted into a table dynamically. Since there'll be quite a lot of rows in the table, I'm trying to implement some paging controls so the user can see about 20 rows at a time and then page through the rest of the rows.

I've seen the example at the following url and I'm trying to get it working:

http://labs.adobe.com/technologies/s...ingSample.html

I've included all my code below.

When I test, The first 20 rows appear but then these 20 rows are repeated another 20 times, so the first 20 rows are duplicated 20 times on the one page, i.e 400 rows are being displayed (if you know what I mean). The paging is also working via the buttons but each of the 20 rows (20 x 20) are being paged simultaneously, and I only want one set of 20 rows to appear at any one time.

Anyone know what I'm doing wrong?

Appreciate any help.
