Expanding Text box Plus line under the box

Using this video:



I made an expanding text box. Now I am trying to have a thin line under the text box that expands as the same time as the box. Using a Link behavior for the X parameter linked to the box does not have the line expand. Is this even possible?

I would create THREE groups:





from top to buttom
• Text , which is … ehm, the text.
• Box, which is a clone of text + that cranked up border filter to create the box
• Line, which again is a clone of Box, squeezed to make the box a line and positioned under the box

when you change the text, both boxes automatically adjust length ....

Kirsten you are the man. I was hoping to make the line another color then the box. What if I made another box a different color but turned it off? I will try using your project. Thank you.

Apply Filter/Colorize and map Black to any other color .............

(and just because Kirsten Dunst is a lil' bit more popular than me, those auto-correctors make me female, grrrrrr It's k_A_rsten &%$§!!! )

Sorry about the wrong name spelling, I know I typed in the right name but I guess the computer decided otherwise. Thank you for you help.
