Pass GET value on top of another

Very basic seeming PHP question here... I have a page to which I'm already passing a value, e.g.: Product.php?type=apples

Now I want a drop down form to pass another value, so i'd end up with something like: Product.php?type=apples&cost=cheap

I've tried putting these in a form that looks like:

<form action="./Product.php" method="POST">
<small>View:</small>
<select name="cost" onchange="this.form.submit();">
<option>Choose Metrics</option>
<option value="cheap&amp;type=<?php echo $typeID?>"></option>

to keep the type variable and add the "cost" variable, but the ampersand gets decoded in the URL string.

Am I going about this the wrong way?

Thanks very much.

<form action="./Product.php" method="GET">
<input type="hidden" name="type" value="your_type_value" />
<select name="cost" onchange="this.form.submit();">
<option>Choose Metrics</option>
<option value="cheap"></option>

First of all, you need to change the method from POST to GET.

Secondly, a second variable, needs a second input field. You could use a hidden field for that, or let the user choose it. (Or do javascript manipulation)

Hidden field

<input type="hidden" id="type" name="type" value="cheap">

This can be achieved with JavaScript too ofcourse!
