Re: [Jmol-users] Attaching a code file

[Sudeep P. <spr...@de...>]

Dear Bob, 

Thank you for your quick responses.

You explained why we get "undefined" when we remove jmolSetDocument(0). But
when we add jmolSetDocument(0), then it doesn't show us the applet at all.
When we check the javascript console, it gives the error, "TypeError-object
(result of expression jmolSetDocument) does not allow calls." Why do we get
this error, and more importantly, what do we change to get the applet to
work. 

You could check our site: people.depauw.edu/jhansen/chem/trialx.htm and
jmollayout.js in the same directory.
