Issue with inherited code.

I've inherited some code and there is an issue where the _START_ value looks like it is stale. Here's the scenario.

1. Page search returns a datatable. At the bottom it displays "Displaying 1 to 200 of 11,000 results"
2. Hit the next at the bottom of the datatable so the custom message displays "Displaying 201 to 400 of 11,000 results"
3. The search parameters are changed and they hit the search button.
4. The datatable is refreshed with the new results, but at the bottom it displays "Displaying 201 to 26 of 26 results".


Does anyone know why the _START_ value is not being set to the correct value? I don't know if showing some code will help or not. If it is please let me know and I'll post anything I can.

Thanks.
