I want to set up swagbucks.com as my default search engine. I added it to the list but the "make default" button cannot be clicked. I think it's a problem with the url I used. This is what I have in the url box now:

http://swagbucks.com/?t=w&p=1&q=%%%

any help?

Google Chrome Plugin
Right-click the search bar at the top of Chrome and choose "Edit search engines," then click the "Add" button.
Enter "Swagbucks.com" in the first two fields, and this string — http://www.swagbucks.com/?t=w&p=1&q=%s — in the third field marked "URL."
Click OK, then highlight the new Swagbucks.com search entry and click the "Make Default" button.
Click close.
