Scipted navigation to open another file

I feel a little foolish asking for help for this simple operation but for the life of me I can't figure out why I can't get a file/script to "hand-off" to another file on the server in WebDirect; internally, the hand-off is smooth and works so there's some thing I'm missing in the scripting or settings.

Order of operations:

1. User logs into the "switchboard" file online. (Works fine)
2. User clicks button to leave switchboard file for Assessment file using the Open File script command. (Nothing happens)

Like I said, "inside" FileMakerPro when I click the button I'm handed off to Assessment, no problem. I have the checkbox ticked in the Privilege set ("Access via FileMaker WebDirect")  in the Switboard and Assessment files, so any ideas where to poke around to see what I'm missing, or what script steps should I use to go to the Assessment file (and closing the Switchboard file)? Open File doesn't work in WebDirect, so....?

TIA for your help!
