Database search dilemma

I have 2 search forms which point to the same results page. The problem is that for the same given search criteria, each form produces a different result. Can anyone tell me why?

FORM 1:

<form id="form1" name="form1" method="post" action="search-box-results-page.php">&nbsp;
<input name="Products" type="text" id="Products" value="" /><input name="WADbSearch1" type="image" class="searchbutton" src="imgs/search.png" />
</form>

FORM 2:

<form name="form1" action="search-box-results-page.php" method="post">
<table cellpadding="2" cellspacing="0" border="0">
<tr>
<td align="right"><label for="Products">Keywords</label></td>
<td><input type="text" name="Products" value="" /></td>
</tr>
<tr>
<td align="center" colspan="2"><input type="submit" name="WADbSearch1" value="Submit" /></td>
</tr>
</table>
</form>

Perhaps I am going blind. Any help would be much appreciated

most likely, the data assist search behavior is set to trigger on the WADbSearch1 submit button.

In one search form this element is submit button, in the other it is an image element type.

An im age element type does not have a value attribute. Instead of passing a value, it passes x and y coordinates of where the mouse clicked it.

the code for triggering a submit button would look like this:

if(isset($_POST["WADbSearch1"])){

to trigger for the image element type would look like this:

if(isset($_POST["WADbSearch1_x"])){

you will need to edit the trigger to use either:

if(isset($_POST["WADbSearch1"]) || isset($_POST["WADbSearch1_x"])){

Fantastic thanks Jason. Thank you!
