Help on htmlText!

Hi guys, i used htmlText to load my html text file to the Flash actionscript but the hyperlinking part is not working.
In my html file, i tried to [COLOR=blue]hyperlink[/COLOR] e.g:
[COLOR=red]<a href=‘’>[/COLOR] to a word, it’s not working and the below text would disappear. However, if i wanted to change the url to this:
[COLOR=red]<a href="[/COLOR][COLOR=red][/COLOR][COLOR=red]? “target=”_blank">[/COLOR]
Then it’s working. So i suspect that it’s the [COLOR=blue]complicated url behind(got the catName=7&artName=…)[/COLOR] that makes the flash unable to read. What should i do?
