Problems inserting script into PHP page

[trashy]

When I attempt to insert this script into my forum index template I get an error and I can't figure out where the problem is.

It is supposedly on line 196. I can't find anything wrong there. Any ideas?

Parse error: parse error, unexpected T_STRING, expecting ',' or ';' in .../Themes/babylon/index.template.php on line 196

187: for (p=0;p<theimages.length;p++){
188: this.postimages[p]=new Image()
189: this.postimages[p].src=theimages[p][0]
190: }
