Error with Google Custom Search. Please help me set this up, Thanks

The plugin "Custom Google Search" does not seem to play nicely with CoursePress. That is ok, I have deleted it.

I tried simply using my Google Custom Search (Adsense) form code in one page and directing the form to my decided action page, using the URL that WP generates as the action page.

Every time I perform a search query, I do not get the Google Custom Search results page. I get the WP search results page with a message saying no results.

I'm confused by this. Please help me understand what is happening and offer a working solution. You can have a look if you like

Thank you in advance
