Search.php - by Real Estate Agents & other variables

Hello! Well, I have been working on this for awhile now and I'm sure it's just something obvious that I'm missing.

Here's my search page test:
http://www.dunhamrealestateservices.com/search2.php

I can search by price, property type & state (and any combination of those 3 fields). However, I can't get an individual search for either agent to show anything by itself or in combination with another field.

For instance, I can search for price from $0 - unlimited + residential + wyoming and I get my 2 test properties. However, when I do the same search and select either one of the agent names - I get "no record found" and there should be 1 listing for each agent.

I have been able to get it to show the agent names... but that's it.

Here's my header code:

// load records
list($homepagesRecords, $homepagesMetaData) = getRecords(array(
'tableName' => 'homepages',
));

and body code:

<form method="post" action="listings.php">

<table border="0" align="center" cellpadding="6" cellspacing="0">
<tr>
<td width="95">Price </td>
<td width="214">
<select name="price_min">

</tr>
<tr>
<td colspan="2">&nbsp;</td>
</tr>
</table>

Thanks for the help!! Tina
