Sorry, but I'm getting confused. Here is my code as it stands now.
<form name="mycart_1_ATC_137" method="POST" action="<?php echo $_SERVER["PHP_SELF"]; ?><?php echo (isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] != "")?"?".$_SERVER["QUERY_STRING"]:""; ?>">
<p>
<input type="hidden" name="mycart_1_ID_Add" value="146" />
<strong class="Grey_Links"> Size</strong><span class="Grey_Links"><strong>
<hidden name="mycart_1_Size_Add" id="mycart_1_Size_Add" value="Small">
<select name="mycart_1_Price_Add" onchange="document.getElementById('mycart_1_Size_Add').value = this.options[this.selectedIndex].text">
<option value="18.00">Small</option>
<option value="18.00">Medium</option>
<option value="18.00" selected="selected">Large</option>
<option value="18.00">Extra Large</option>
<option value="18.00">2X Large</option>
<option value="19.00">3X Large</option>
</select>
<br />
<br />
Quantity</strong></span>
<input type="text" name="mycart_1_Quantity_Add" value="1" size="4" >
</p>
<p> </p>

<input type="image" src="WA_eCart/Images/Pacifica/Btn1_EN_addtocart.gif" border="0" value="Add to Cart" name="mycart_1_ATC" alt="Add to Cart">

</form>
