[Javascript] Need help with a javascript issue

[Alejandro Celery]

Hi, mi name is Alejandro.
I can´t get netscape communicator 7.1 to follow a link properly on a certain webpage. IE does so correctly. It is to send text messages to cell phones. I checked the page source and this code i´ve pasted appears in black. Does this mean that this code is not NS compatible? Is there any way to fix this, or the page was designed with only IE in mind?
This is my first post to the list, I apologize if i infringe any house rules. Thanks for your time.

Saludos (greetings).
Alejandro.
