HTMLSelect gives a wrong ouput?

I am using the bellow code. With opA or opD works but not with opB or opD. Perhaps because in the output B and C is used 10^-6! But why?. Also, in OpB and optC the menu reset to OptA .

enter image description here enter image description here

<%@ page language="java"  %>
<%@ taglib uri="/webMathematica-taglib" prefix="msp" %>
<html>

<head>
<title>TITULO</title>
<link rel=stylesheet type='text/css' href='css/estilo1.css'>

</head>
<body bgcolor="#ffffff" >

<form name="formulario" action="biokmodfit2.jsp" method="post">


Choose one option: 
<msp:evaluate>
HTMLSelect[{"OpA","OpB","OpC","OpD"}, {2.4*10^-5, 0.32*10^(-5), 2.1*10^-6, 4.2*10^-5}, "dcf", SelectedValues -> {$$dcf}]
</msp:evaluate>
Or
<INPUT TYPE="TEXT" NAME="dcfOptional" ALIGN="LEFT" SIZE="35" 
VALUE="<msp:evaluate>  MSPValue[$$dcfOptional,"0.0"] 
</msp:evaluate>"
/>
<INPUT TYPE="checkbox" NAME="dcfOptionalChbx" >
</td></tr>

If you are getting your HTMLSelect values from WL output, change it to a List of strings. This at least curtails the error you recieved. If you wish values < 10^-6 to be formatted in DecimalForm or NumberForm then manipulate what is retruned. Try pasting "0.32*10^(-5)" in a WL session and see what is returned (without the quotes).

The following is a modification to the last msp:evaluate 

<msp:evaluate>
If[$$dcfOptionalChbx==="on", $$dcf = $$dcfOptional];
temp = MSPBlock[{$$dcf}, $$dcf];
temp2 = MSPFormat[NumberForm[temp, ScientificNotationThreshold -> {-8, 6}]];
HTMLTableForm[temp2]
</msp:evaluate>
<msp:evaluate>
temp3 = NumberForm[temp, ScientificNotationThreshold -> {-8, 6}];
HTMLTableForm[MSPFormat[temp3]]
</msp:evaluate>

Two similar path to change the threshold when you start to see number in the form 10^-x.
