Atahualpa options not running

I have been using Atahualpa 3.5.3 for a long time on my blog http://sanjeev-sharma.com
Yesterday I made some changes in the Configure excerpts options of the theme. It had to do with the fact that I wanted <> tag not stripped. The exact option that I filled in was <script type="text/javascript"> After updating the theme options, I find that:

1. The tags are getting stripped in the sense that in the excerpts the ads are showing which I did not want, and worse
2. The Atahualpa theme options are now not getting selected. What I mean is that when in the Appearance tab on my dashboard I click on the "Atahualpa theme options", I get to see the list of all the Atahualpa theme options, but when I choose anyone of them, nothing happens. The left side lists all the options but the right side is all blank. I have attached a screen shot of the page.

I need help to resolve this.

best regards

Sanjeev
