I'd appreciate some advice re Amazon Ads on Thesis.

I've been trying to place a series of Amazon block ads on the sidebar of My Test Site using
This Guide but my ads are not clickable. Any suggestions?

Here's how I'm entering my code:

The first part of the code is the code supplied by Amazon and the second part of the code from <img src= .. is where the Amazon image is stored on my server.

The four ads are all the same at the moment but it is only a test site.

Thanks for any help
