Drop down list link problem

I have a problem with drop down list.
I want to play video by clicking on one of the links in drop down list, but it always adds this sign(') before video link.

<option value="video.swf">Video1</option>
so it looks like www.mywebsite.com/'video.swf and message it cannot be found.

also it doesn't read html pages.
for example http://www.mywebs.com/mynew.html


Thanks

Could you post a little more information? What doctype are you using? and can I see the code for this whole link? (you can remove anything sensitive and replace with what ever, I just want to see the full code). Thanks
