Help posting correct Array[value] to JSP page

Question

Hello,
Can someone please tell me what is wrong with this? I am posting the following page (only a portion of the page is listed below) to another jsp page. It consists of a listing of books for sale. Next to each book is a separate "add to cart" button. I want to send the corresponding "isbn" (indexed in an Array) to the next page. When I add print stmts for each record, I can see that the correct isbn is attached to each book.
The problem is that when I post this to the next page, the formparm for isbn is always the 1st isbn in the array, instead of the selecgtedIsbn. Why???
Thanks in advance!
<CODE>
<% for(int i=0; i < isbnValues.length; i++) {  %> 
<TABLE>
<% if ( isbnValues[i] != null) { %>   
<tr>
<td> <B><%= titleValues[i] %> </B> </td>     
<INPUT TYPE="HIDDEN" NAME="selectedIsbn" VALUE="<%= isbnValues[i] %> "></INPUT>
<INPUT TYPE="HIDDEN" NAME="selectedPrice" VALUE="<%= priceValues[i] %> "></INPUT>
<td align="right"> <i>Price: </i>
     <%      DecimalFormat df = new DecimalFormat("$#,##0.00");
          String strPrice = df.format(Double.parseDouble(priceValues));
     %>
          <%= strPrice %>     <br>
</td>
<td align="right"><i>Quantity:</i>      
     <INPUT TYPE="TEXT" NAME="qty" VALUE="1"></INPUT> <br> </td>
<td align="right">
     <INPUT TYPE="SUBMIT" VALUE="Add to Shopping Cart"></INPUT> <br>
</td>
</tr>
<% } %>     <%-- end if isbn --%>     
</TABLE>
<% } %> <%-- end for loop --%>     
</CODE>

Hi,
I have the indexes, but they were somehow removed when I posted the code. I used the wrong tags.
I used the right tag and added spaces around the [" i "].
Let's try again... Here's the code:
<% for(int i=0; i < isbnValues.length; i++) {  %> 
<TABLE>    
<% if ( isbnValues[ i ] != null) { %>   
<tr>
<td>  <B><%= titleValues[ i ]  %> </B> </td>     
<INPUT TYPE="HIDDEN" NAME="selectedIsbn" VALUE="<%= isbnValues[ i ] %> "></INPUT>
<INPUT TYPE="HIDDEN" NAME="selectedPrice" VALUE="<%= priceValues[ i ] %> "></INPUT>
<td align="right">  <i>Price: </i>
     <%      DecimalFormat df = new DecimalFormat("$#,##0.00");
          String strPrice = df.format(Double.parseDouble(priceValues[ i ]));
     %>  
          <%= strPrice %>     <br>
</td>
<td align="right"><i>Quantity:</i>                 
     <INPUT TYPE="TEXT" NAME="qty" VALUE="1"></INPUT>   <br> </td> 
<td align="right">
     <INPUT TYPE="SUBMIT" VALUE="Add to Shopping Cart"></INPUT> <br>
</td>
</tr>
<% } %>     <%-- end if isbn  --%>     
</TABLE>
<% } %>      <%-- end for loop  --%>
