When I run W3C verifier against my strict XHTML 1.0 I get the following error
complaining about a less than sign inside my <script> tag.
1. Warning Line 52 column 18: character "<" is the first character of a
delimiter but occurred as data.

for (i = 0; i < apanels.length; i++) {

This message may appear in several cases:
* You tried to include the "<" character in your page: you should
escape it as "<"
* You used an unescaped ampersand "&": this may be valid in some
contexts, but it is recommended to use "&amp;", which is always safe.
* Another possibility is that you forgot to close quotes in a
previous tag.

I import js and css files, but can't figure out why the verifier would be
complaining about a "<" inside <script ..> </script> tags.

Thanks for any help resolving this.
