Execute javascript code on a webpage with VBA

Hi, I am trying to make VBA execute javascript but I am probably doing something wrong, so I would be glad if anyone could help me....
Basically this is the source code of the javascript:

Please Login or Register  to view this content.

Actually it looks like that:

Please Login or Register  to view this content.

The code I tried to use in Excel VBA was:

Please Login or Register  to view this content.

But it doesn't work. What it should do is to open a menu on the website.

Unfortunately, there is no way to access the website for you, because it is on Intranet. Also I wasn't able to find anything similar on the Internet.
But I hope that you will still be able to help me.
I would be very grateful to you!
