Javascript problem - concatenation operator

I'm trying desperately to make my script work in Opera.  I have the 
latest (9.1, just upgraded from 9.0 to see if it fixed this problem but 
to no avail).

Opera fails with "script compilation error" several times throughout
my 
entire script.  It seems that whenever I try to concatenate two strings 
with the "+" operator, Opera doesn't even see the operator!  In the 
error message, it shows my code with the plus character removed!

Example (this goes all in one line):
ieProp += iePropWords[i].substring(0, 1).toUpperCase() + 
iePropWords[i].substring(1);

Fails with error message:

Syntax error while loading: line 13 of linked script blah blah
ords[i].substring(0, 1).toUpperCase()  iePropWords[i].substr
--------------------------------------^

Any ideas what the problem could be?  This error occurs over and over 
throughout my script (which works fine in Gecko, KHTML, and IE).  Each 
time it shows my code sans plus sign and marks the spot where the plus 
sign should be as the origin of the error.

Thanks,

Okay. sample page at <http://www.designregime.org/~jeremy/foodark/> - 
check out the error messages and compare them to the JS source files 
(<http://www.designregime.org/~jeremy/foodark/scripts/constraintSlider.js>

for example, a double slider control) and verify for yourself that those 
plus signs do, in fact, exist.

I'm really puzzled on this one - it's kind of frustrating because 
there's no way I can really fix it without knowing what the problem 
actually is.  Thanks for any advice you can provide.

Okay, this is where things get weird.  Just for completeness, I tested 
it on Opera 9.01 Mac.  And it works like a charm.

I'll get a coworker to install it on their Windows machine.  Maybe it's 
just my computer?  I should uninstall/reinstall I suppose.

It's comforting that it probably works for everyone else, though.

Yep, works fine on my coworker's machine (well - almost fine.  There are 
still some graphical glitches that don't occur on any other platform, 
and the "Learn More" pop-up bubbles do not function correctly).

In any case, I'm reinstalling opera now.  I guess it was just my 
machine.  So this is no longer an issue for opera.page-authoring :P

Sorry if I wasted anyone's time.

We'd need to see a demo page. I've never seen that sort of problem before.
