Hi,
I use FrameMaker7.0.
I am trying to create a hyperlink to a webpage.
Example: When the user clicks on the word 'Introduction' it should open the Adobe home page.
So this is how I did it:
Place the Insertion point before I of the word "Introduction".
1. Go to Special -> hypertext.
2. In the pop up menu, selected "Go to URL" from the command list.
3. Typed the URL (all lower case.
4. Checked "Validate upon insertion".
5. Clicked "New Hypertext Marker".

I got the error messgae that it was not a valid hypertext command.
But a marker was inserted(inverted T)near I.

1. Why is this error message displayed?
2. I read something about preparing the text area by changing the character format to "As Is" - Can somebody please explain this concept to me?
3. How do i view the link ?
