Form-Cart Linking Question

[juhko5]

Total newbie, but here goes.
I have a site in which products are associated with "Add to Cart" buttons which I simply created with a form in Dreamweaver. It looks like this:
<form action=&quot;

http://&quot;;

method=post>
<font size=&quot;3&quot;>
<select
name=&quot;select5&quot; size=1>
<option value=&quot;ITEMX&quot; selected>Item X
</select>
<input type=hidden name=&quot;0:finoptnum25&quot; value=2>
<br>
</font><span class=&quot;Text&quot;><font size=&quot;3&quot;>Quantity</font></span><font size=&quot;3&quot;>
<input type=text size=2 name=&quot;0:qnty5&quot; value=&quot;1&quot; >
<input type=hidden name=storeid5
value=*1ee794740f17a3216a70c5c74ccf04f4f7>
<input type=hidden name=dbname5 value=products>
<input type=hidden name=function5 value=add>
<input type=hidden name=itemnum5 value=0>
<input name=&quot;submit5&quot; type=submit value=&quot;ADD TO CART&quot;>
</font> </form>
I am curious how I could get this to link to a shopping cart through Miva. I realize I have to code in the necessary Item information that Miva understands, but am not sure how or where...

Any help would be greatly appreciative.
I am using Miva Merchant 4.

Thanks very much,
Juhko
