Quick Upload Create Directory Error

Hi, I am using the Coldfusion versions of fckeditor 2.6.4 and ckfinder 1.3.3 and I am having problems with dynamic directories on upload. I am using ckfinder as part of fckeditor. I have defined a dynamic path based on session variables in config.cfm for ckfinder.

Now, if I click on link or image in the fckeditor, I have the option to browse server or click on the upload tab. Clicking on browse server and using the upload feature there works fine whether or not the directory already exists or does not. The upload tab works fine if the directory exists but if it does not, I get an alert that says "undefined".

Any suggestions on what I am doing wrong?

Thanks!
