Getting an <iframe> in Watir

I am new to Ruby and Watir. I need to access a frame (iframe) in a
popup window and click a link in the frame. The frame tag is as

If I ie.show_frames I get the following:

there are 1 frames
frame index: 1 name:

Here is my code:

ie = Watir::IE.attach(:url,“mypage.jsp”) #
ie.frame(:id, “facframe”).link(:text, “mylink”).click

Apparently, you can not access a frame by its id. If there is no
“name” attribute, how do you get access to the frame?

ruby 186-25

Any ideas would be great. TIA.

What does ie.frame(“facframe”) yield?
