Buttons not connecting to detail pages??

if I click on one of my button links (such as);

items_Detail.php?ItemID=4

I receive this message:

Page not found

The page you are looking for might have been removed,
had its name changed, or is temporarily unavailable.

Please try the following:
If you typed the page address in the Address bar, make sure that it is spelled correctly.

- Click the Back button in your browser to try another link.
- Use a search engine like Google to look for information on the Internet.

HTTP 404 - File not found

If I go to my search page, where there are several products listed (here is the link);

items_Results.php?S_ItemName=&S_ItemCatID=&Search.x=31&Search.y=13&Search=Search'

I receive this message:

Unknown column 'ParentChildID' in 'field list'

I do not understand? Everything with my MySQL Database and my PHP pages seem to work except for the actual product detail pages will not link. The ID #'s match the Database ItemID so if someone could please break this down for me it would be very helpful!

your links to the detail page should point to:
items_Detail.php?ItemID=4

instead of:
items_Detail.php?ItemID=4



can you send a copy of the detail page so i can investigate the cause of the error.

Yes, that is exactly what it was!!!!

Thank you!

Now I have some weird new problem I will make a new post.....
