Tengo un formulario ... quiero mostrar los datos de mysql table ... el problema es que la instrucción de consulta SQL no muestra los datos ... ¿alguna idea? ¿Creo que el error puede deberse a la instrucción AND en la línea de consulta SQL?

<code>  <form method="get" action="submit.php">

   Number of Bedrooms: <select name="bedrooms">
   <option selected value='#'>--Choose Number of Bedrooms--</option>
   <option value="2">2</option>
   <option value="3">3</option>
   <option value="4">4</option>
   <option value="5">5</option>
   </select>


   Number of Occupants:  <select name="sleeps_min">
   <option selected value='#'>--Choose Number of Bedrooms--</option>
   <option value="2">2</option>
   <option value="3">3</option>
   <option value="4">4</option>
   <option value="5">5</option>
   <option value="6">6</option>
   <option value="7">7</option>
   <option value="8">8</option>
   <option value="9">9</option>  
   <option value="10">10</option>
   </select>

   Availability:  <select name="availability">
   <option selected value='#'>--Select Availability Period--</option>
   <option value="All year round">All Year Round</option>
   <option value="New Year Availability Only">New Year</option>

   </select>
   <input type="submit" value="submit" />
    </form>
