Need help eliminating "Warning: JavaScript Window" text in message

I've recently upgraded from Acrobat 5 to 8 Pro. Acrobat 8 introduces trustedFunctions and privileged content which is causing a warning message for all the message boxes in the PDF. I've also looked through the JS for API Acrobat API Reference and others but can not find a real example for the app.alert function. Here's the code that's causing the trouble. Would someone please show where to add the trustedFunction calls and the app.beginPriv() and app.endPriv()? I can then apply it on the other calls. This PDF is going out to external customers and that warning message shouldn't ever be seen by a client.

Thanks in advance,
Charlie
