I don't see your query to know what you expect in $results

Do you know that you've any data to show at all?

Further help: when you get the 'blank page', you should be able to view its source (that is, what's on the page). In FireFox, for example, you right click on the page and then select "view page source". Now you can see what, if anything, came back. It may be that it will show you an error message that's not rendered on your screen (for example, from a failed TSQL query).

Other error may also be made visible, such as undefined index(s).

Your first task is to see if you even get data back in order to display on the page.
