I am trying to add the UDT into the conttent pane that already has text/HTML module.  The content page has a few descriptive paragraphs and a table of all products.  I wish to insert into the middle of the page, etween the paragraph and the table, a UDT that does not show results until searched.  My reason is that while the table has only the product name, the UDT has expanded information for each product.  I wish to allow people to either look at only a list, or to search.  SO how do I insert the UDT in the middle of the content pane?  Do I need to seperate out the paragraph from the table and insert a seperate module between?

I agree with Pete, however another option would be using Header and Footer text, which can be specified in module settings (of an module) and gets injected above / beneath the content.

Google can only index the returned html content, so if your data is hidden, it will not be included (http://en.wikipedia.org/wiki/Deep_Web).
