i'm trying to set up a master-detail-grid. master grid works fine but when i click on a row to populate the detail-grid, nothing happens. well for now details-grid is not even showing on the main page. i put the details-grid code in a separate file to check whether code was working or not and it seems its fine. so it seems that the only time detail-grid code is not working is when i have it togather with the master-grid code on the main page.

below is how i have it set up but only the mater-grid shows the records and detail-grid is not even visible. i have tried every possible option to make it work but no luck so far.

also for now i'm not passing any parameters to master_subgrid.php page as for now i'm only trying to make it visible and work on the main page where master-grid is. sql-query parameter is hard-coded and it does return rows [on the separate page which is tester.html]
