Problem with JavaScript Array with 1 Element

Hi,

This is possibly more of a JavaScript question, but I wouldn't be doing all this JS if it weren't for Ajax anyway, so here goes...

Im registering a client-side array when a webform first loads.  The array's contents are dynamic.  Everything works fine as long as the array winds up having at least 2 members.  When the array has only one member, however, JavaScript says it's undefined.  I look in the page's source, however, and sure enough, there it is.

Any suggestions?

Thanks.
