Creating search form that will query SQL database and display results on a custom block

I am a new to Drupal and have learnt about custom blocks. Basically, I am trying to create a search page where on the left column will have all the filter/search criteria. On the right column the results will be displayed in a specified format in a custom block. Not sure where to start on this work. I have my back end ready with all the parameters going in correctly and results are displayed out of a stored procedure. Not sure about how to wire up the front end filter criteria fields with backend SQL parameters.

Can't get past first install page

Hi, I'm setting up a server for my own testing, it's a vps running windows, with a manual install of php, sql server etc

I can't seem to get past the first install page - where the language is selected, clicking 'save and continue' just loops me back to the same page - there are no errors that I can see.

Thought it might be more on the server or php config side rather than drupal side, so just installed wordpress as a test and it went in no problems.

Does anyone know what could cause this problem? have copied the default.settings.php to settings.php to no avail
