i think your problem is here:
you don't have to parse them as strings, as they are allready strings. Bu this s not causing the problem. You have a dollar sign before "Scontent" and "title", i think this has to be removed. this is what should be there:
also add 'or die(mysql_error());' after every mysql_query(), that way you can check what mysql returns as error.
