Thanks for the suggestion. I did add that line. I also found my other problem. I shouldn't have put the <cfwddx tag within the javascript, but after i populated the coldfusion array.

Here are the code lines I put after populating the repositoryArray :

...

The CF repositoryArray is populating correctly. Regarding declaring jsrepositoryArr ay prior to the CFWDDX statement, The examples I've seen of CFWDDX didn't show that prior declaring of variables was required. I tried declaring the variable jsrepositoryArr ay first and it still doesn't work.

Oops. Copy-and-paste mistake. Here's the beginning <script> tag:

<script language="javas cript" type="text/javascript">

Thanks for pointing that out.

I am coding in Coldfusion MX7 and using Javascript for some of the functionality. The basic functionality I'm coding is, based on a value the user chooses from a dropdown box, I populate address fields with the associated data. I am using the onChange attribute of the dropdown box for the call to a Javascript function. I prepopulate a Coldfusion array with the address data and am using cfwddx to convert the Coldfusion array to a Javascript array....
