For anyone having problems with buttons, I'll tell you what I did for blogger. I don't know if this helps everyone, but I know a lot of people have blogger so... :)
1) Save the button (to your server) and then upload it to like, flickr or something like that.
2) Go to the picture, and right click on it and select "copy image location"
3) Go to "Customize" and click "add html or code."
4) Type this: (a href="http://knittersscavengerhunt.blogspot.com/") (img src="paste the image location here") (/a) BUT instead of these ( ) use these < >. In every space. Make sense?
Hope this helps some people! :)
Btw, I posted once, I'm Krystal from Ohio, and my blog is Yarn Mafia, check us out! :)
