Form assistance needed

This form does not send the “Product Price” to the shopping cart in this format. However, when I add the following line:
<input type=”hidden” id=”ProductPrice” value=” 35.00″ name=”ProductPrice”>
the 35.00 price gets sent.

Please help.

<form action=”https://cart.net/securecart.asp” method=”post” name=”selection_form” >
<select id=”selection” name=”selection” size=”1″>
<option name=”ProductPrice” id=”ProductPrice” value=”35.00″ SELECTED>50 Grams $35.00</option>
<option name=”ProductPrice” id=”ProductPrice” value=”75.00″>100 Grams $75.00</option>
<option name=”ProductPrice” id=”ProductPrice” value=”300.00″>1 lbs. $300.00</option>
</select>
