Export one Excel Worksheet to pdf using javascript

Greetings All,
 
I've been working on a script to automate the production of a single pdf that has pages inserted from multiple sources (Word, Excel, and other pdfs). The script exports on the fly from those sources not already saved as a pdf. I'm running the script as a menu item at the app folder level through a trusted function. This issue I am having is that I am not able to specify which worksheet I want to convert to pdf from Excel. Here is an excerpt:
var test = app.openDoc({
cPath: "C:/TestGraphs.xls",
cDest: "TestChart",
bUseConv: true
});
The cDest property doesn't seem to be working for me. Is there a better way to do this? Any suggestions are appreciated. Oh, I am developing this in Acrobat 9 Pro but need it to run in Acrobat 9 Standard.
 
Thanks!
