setTimeout on enter JavaScript firing immediately w/o delay

Hello,

I am trying to trigger an action on the final slide of the project, where the project closes after a period of time.

The JavaScript that is triggered on enter is:

setTimeout(cpCmndExit = 1, 5000);

But Captivate will just ignore the timeout and exits immediately.

Any ideas?
