Hi there

I'm trying to post details from a html form to a php page which will display the results based on the selected criteria. Below is the html and php code I'm using and the sql error that I'm getting. Is it that I have something wrong in my sql statement.

I'd appreciate any help with this.

Form.html

Code:
<form action="output.php" method="POST">
<table border = "0" style ="width:300px; height:266px;background-color:#ebb6f1;">
<tr>
<td colspan = "2">
<h3>Search for a Partner:</h3>
</td>
</tr>
<tr>
<td>Show Me:</td>
<td>
<select name="gender" style = "width:200px;">
<option value="female">female</option>
<option value="male">male</option>
</select>
</td>
</tr>
<tr>
