I did just catch the first issue -- the improperly closed double quote. I switched the 'main' quoting back to  qq{} to ease up on the toothpick syndrome. Fixing that ... didn't help.

the values i've been using for the three vars don't need escapes. i can tackle that issue once i have a working repsonseText replacer. they've been simple strings.

$('overide_123').innerHTML is valid javascript. the same handler uses it for another (working) part of the application.
