Made a syntax error in sidebar- can’t fix it.

I was editing my sidebar file, but made a syntax error, so the blog isn’t functioning properly. But the error is listed on page one of my blog. I don’t have the original sidebar file on my hard drive. I did download the sidebar file after making the error. However I can’t figure out what code needs to be changed to make the blog work again. Can someone help by checking inthetext.com. If you can fix it by just putting in a few code characters, that would be fine, or you could tell me how to do it. Thanks.
