Search for the call to sendToLinkblog. I've pasted the text in below.
escapeParam is doing its job correctly on item.title, but not on item.body. I can see this by looking in Firebug, as well as in the behavior of the app. Calls to sendToLinkblog for items that have one or more single-quotes in their title fail, presumably because of a syntax error, due to the unescaped single-quotes.
Update: Problem solved, though no one person had the answer. Nik Cubrilovic suggested adding a call to "escape" at the beginning of the escapeParam routine. But this just had the effect of doubly-encoding the params, and didn't solve what was clearly a syntax problem in the call to sendToLinkBlog. However, it gave me an idea. I could do the URL-encoding in the call to sendToLinkBlog, and solve the single-quote escaping problem, and eliminate the escaping in sendToLinkBlog. Bing! It worked. So now I'm ready to move on to the next problem/bug. Thanks as usual for the brain-trust help.
