webElements: WEAutoRefresh not working in report

I'm using this webElement to provide automatic refresh for a Crystal Report (using version 2013).  The server is set up for html pass-through, and webelements has been deployed on the server.  I'm testing on a simple report, without sub-reports, but the official report contains 3 sub-reports.  We need the refresh to occur in the original view, that will be resized for a wallboard monitor, and thereafter will not have any interaction.

The code for the WEAutoRefresh formula field is:

Stringvar path:= WETargetPath("rpt", "CUID", "ASp9t6WlwPtIsjmArf4Anpk", "");

Stringvar autoref:= WEAutoRefresh(15, path);

The behavior I get when running the report in server view mode is: another Chrome window comes up on the first refresh, but it's empty and untitled.

And, this was the same behavior using the "Name" ID-Type, and report name instead of CUID.

Thanks!
