That's never been a problem.

Trying to install a downloaded product.

Even trying to grok some simple concepts. e.g. one can specify parameters 
on a Script (Python) object, but nothing I can find explains how these 
parameters get values. In looking thru the Shopping Cart Example I found a 
form specifying in part

<form action="addItems">
<input type="text" name="orders.quantity:records" ...

where addItems is a script in the same container, and addItems specifies 
orders, REQUEST=None as parameters. What's missing for me is the 
relationship between the form and the parameter list.

In another example I experimented with a Page Template calculateForm:
...
   <form action="calculateSum">
     <input type="text" name="a" tal:attributes="value request/a"><br>
     <input type="text" name="b" tal:attributes="value request/b"><br>
     <input type="text" tal:attributes="value result"><br>
     <input type=submit value="Submit" name="Next10">
   </form>
...
where calculateSum is script:

## parameters a,b
sum=int(a)+int(b)
return container.calculateForm(result=sum)

After clicking Submit the form reappears, with the values for a and b 
filled in. What is the magic that associates the values I entered for a and 
b with the request to display the form again?
