sql query problems

[adult.swim]

I have created a html form page, and a corresponding process page.

My form gets input from the user, and compares it to the fields in my database. If the input

in the form matches a field in the dB, the process page returns the corresponding record.

The problem is only the address input for the form works correctly. All of the other fields

return all the records in the dB. I've tried varying the SQL query code many times.

My question is why does only the address search work as opposed to the other input fields?

search.php: form

[code]

<form id=\"search\" method=\"post\" action=\"process.php\">

<table class=\"search1\">

<tr>
<th><label for=\"pad\">Pad Number</label></th>
<td><input id=\"pad\" name=\"pad\" type=\"text\" class=\"inputbox\" size=\"50\" /><br

/></td>
</tr>

<tr>
<th><label for=\"mls\">MLS Number</label></th>
<td><input id=\"mls\" name=\"mls\" type=\"text\" class=\"inputbox\" size=\"50\" /><br

/></td>
</tr>

<tr>
<th><label for=\"address1\">Address</label></th>
<td><input id=\"address1\" name=\"address1\" type=\"text\" class=\"inputbox\" size=\"100\"

/><br /></td>
</tr>

<tr>
<th><label for=\"city\">City</label></th>
<td><input id=\"city\" name=\"city\" type=\"text\" class=\"inputbox\" size=\"100\" /><br

/></td>
</tr>

<tr>
<th><label for=\"zip\">Zip Code</label></th>
<td><input id=\"zip\" name=\"zip\" type=\"text\" class=\"inputbox\" size=\"15\" /><br

/></td>
</tr>


</table>

<br />

<table class=\"search2\">

<tr>
<td>

<input type=\"Submit\" value=\"Submit\" style=\"width: 60px; font-size: 1.0em; padding: 2px

10px 2px 10px; margin: 5px 3px -3px 3px; background-color: #115492; float: left; border:

solid 1px #023666; color: #ffffff; text-decoration: none;\" />

<input type=\"Reset\" value=\"Reset\" style=\"width: 60px; font-size: 1.0em; padding: 2px

10px 2px 10px; margin: 5px 3px -3px 3px; background-color: #115492; float: left; border:

solid 1px #023666; color: #ffffff; text-decoration: none;\" />

<input type=\"hidden\" name=\"op\" value=\"do\" /><p>&nbsp;</p>
</td>
</tr>
</form>

</table>
