Hi KarDav28 and welcome to our community
Well, a number of things could be happening.
* Is this the only effect you have applied? If you choose two
or more effects, some aren't compatible with others. In that case,
t's all trial and error to see what works and what doesn't.
* Are you running your WebHelp on a browser that understands
DHTML?
* Have you possibly disabled JavaScript in your browser?
Cheers... Rick
