technical difficulties

All I wanted to do was add a little weather script to my blog, and now the whole template is messed up. Because of the upgrades blogger has made, I had to upgrade my template to be able to use the modular template functionality. I got my weather script, but I lost all of the customization I had done to my template. OK, I admit I saw the warning, but didn't exactly process it. I should have just done it in html! Oh well, I picked a stock template for now and I will decide what to do later. It is still my blog and all of the content remains.
