Select list not setting a return value

Question

I have defined a select list based on a named LOV. With the default values for the SOURCE section I do not seem to be getting a value returned, as indicated in the following debug output:
0.05: parse query
0.05: binding: ":P1_SALESMANAGER_SHOW"="P1_SALESMANAGER_SHOW" value=""
0.05: print column headings
0.05: rows loop: 15 row(s)
no data found
If I change the Source Type to SQL Query and enter the query in Source Value or Expression I get the behaviour I would expect that the value returned is always the first row returned by the query, no matter which one I pick from the list.
What do I need to set so it behaves correctly?
Thanks

How do I generate all the page item attributes to send you? What do you mean by "see the page" - do you want me to submit the generated HTML source?
In the meantime, I have dropped the select list item and am now re-creating it as follows:
- Click the Item Create icon
- Choose Select List
- For Select List Control Type, accept the default of Select List and click Next.
- Item name = P1_SALESMANAGER_SHOW and click Next
- Choose a named LOV, enter null value / text and click Next
- Accept default item attributes and click Next, then Create Item
This is exactly in accordance with the instructions for the example page in Chapter 2 of the 2-day Tutorial.
Run the page, exactly the same result. Clicking Debug shows that P1_SALESMANAGER_SHOW .value is set to null, even though I have picked one of the displayed values.
I need to do a proof-of-technology demo of HTMLDB to my managers this week so would really appreciate your advice to get this going.
Thanks,
