gary, you had a purpose and pursued it to the end, so well done. I just pointed out an approach.

Trying to fit everything into a line is tricky so the next approach is to call a user-defined function that you would place in the Page / Website HTML Code (head). The call for the function would be in the Link: javascript:userFun(xyz);.
Once you get the hang of it, you can populate an IFRAME with a different source, stop a video, play some music, change the background or force a Variant jump, animate something or all the the previous. Second-guessing Xara is the hard part!
